34 / 40 page  ADIS16489 Data Sheet Rev. B | Page 34 of 40 Z-AXIS ACCELEROMETER ALARM (ZA_ALM_MAGN) Table 186. ZA_ALM_MAGN Register Definitions Page Addresses Default Access Flash Backup 0x03 0x32, 0x33 0x0000 R/W Yes Table 187. ZA_ALM_MAGN Bit Definitions Bits Description [15:0] Z-axis accelerometer alarm threshold settings, twos complement, 0 g = 0x0000, 1 LSB = 0.25 mg The ZA_ALM_MAGN register (see Table 186 and Table 187) contains the alarm threshold for the z-axis accelerometer, when ALM_ CNFG_1[7] = 1 (see Table 172). This alarm is associated with the alarm flag in ALM_STS[5] (see Table 20). BAROMETER ALARM (BR_ALM_MAGN) Table 188. BR_ALM_MAGN Register Definitions Page Addresses Default Access Flash Backup 0x03 0x3A, 0x3B 0x0000 R/W Yes Table 189. BR_ALM_MAGN Bit Definitions Bits Description [15:0] Barometer alarm threshold settings, twos complement, 0 g = 0x0000, 1 LSB = 40 μbar The BR_ALM_MAGN register (see Table 188 and Table 189) contains the alarm threshold for barometer, when ALM_ CNFG_2[7] = 1 (see Table 174). This alarm is associated with the alarm flag in ALM_STS[11] (see Table 20). FIRMWARE REVISION (FIRM_REV) Table 190. FIRM_REV Register Definitions Page Addresses Default Access Flash Backup 0x03 0x78, 0x79 Not applicable R Yes Table 191. FIRM_REV Bit Definitions Bits Description [15:12] Firmware revision binary coded decimal (BCD) code, tens digit, numerical format = 4-bit binary, range = 0 to 9 [11:8] Firmware revision BCD code, ones digit, numerical format = 4-bit binary, range = 0 to 9 [7:4] Firmware revision BCD code, tenths digit, numerical format = 4-bit binary, range = 0 to 9 [3:0] Firmware revision BCD code, hundredths digit, numerical format = 4-bit binary, range = 0 to 9 The FIRM_REV register (see Table 190 and Table 191) provides the firmware revision for the internal firmware. This register uses a BCD format, where each nibble represents a digit. For example, if FIRM_REV = 0x1234, the firmware revision is 12.34. FIRMWARE REVISION DAY AND MONTH (FIRM_DM) Table 192. FIRM_DM Register Definitions Page Addresses Default Access Flash Backup 0x03 0x7A, 0x7B Not applicable R Yes Table 193. FIRM_DM Bit Definitions Bits Description [15:12] Factory configuration month BCD code, tens digit, numerical format = 4-bit binary, range = 0 to 2 [11:8] Factory configuration month BCD code, ones digit, numerical format = 4-bit binary, range = 0 to 9 [7:4] Factory configuration day BCD code, tens digit, numerical format = 4-bit binary, range = 0 to 3 [3:0] Factory configuration day BCD code, ones digit, numerical format = 4-bit binary, range = 0 to 9 The FIRM_DM register (see Table 192 and Table 193) contains the month and day of the factory configuration date. FIRM_ DM[15:12] and FIRM_DM[11:8] contain digits that represent the month of the factory configuration in a BCD format. For example, November is the 11th month in a year and is represented by FIRM_DM[15:8] = 0x11. FIRM_DM[7:4] and FIRM_DM[3:0] contain digits that represent the day of factory configuration in a BCD format. For example, the 27th day of the month is represented by FIRM_DM[7:0] = 0x27. FIRMWARE REVISION YEAR (FIRM_Y) Table 194. FIRM_Y Register Definitions Page Addresses Default Access Flash Backup 0x03 0x7C, 0x7D Not applicable R Yes Table 195. FIRM_Y Bit Definitions Bits Description [15:12] Factory configuration year BCD code, thousands digit, numerical format = 4-bit binary, range = 0 to 9 [11:8] Factory configuration year BCD code, hundreds digit, numerical format = 4-bit binary, range = 0 to 9 [7:4] Factory configuration year BCD code, tens digit, numerical format = 4-bit binary, range = 0 to 3 [3:0] Factory configuration year BCD code, ones digit, numerical format = 4-bit binary, range = 0 to 9 The FIRM_Y register (see Table 194 and Table 195) contains the year of the factory configuration date. For example, the year, 2013, is represented by FIRM_Y = 0x2013. PAGE 4 (PAGE_ID) Table 196. PAGE_ID Register Definition Page Addresses Default Access Flash Backup 0x04 0x00, 0x01 0x0000 R/W No Table 197. PAGE_ID Bit Assignments Bits Description [15:0] Page number, binary numerical format |
