DS22072A-page 11 MCP3425 5.2 Configuration Register The MCP3425 has an 8-bit wide configuration register to select for: PGA gain, conversion rate, and conver- sion mode. This register allows the user to change the operating condition of the device and check the status of the device operation. The user can rewrite the configuration byte any time during the device operation. Register 5-1 shows the configuration register bits. REGISTER 5-1: CONFIGURATION REGISTER R/W-1 R/W-0 R/W-0 R/W-1 R/W-0 R/W-0 R/W-0 R/W-0 RDY C1 C0 O/C S1 S0 G1 G0 1 * 0 * 0 * 1 * 0 * 0 * 0 * 0 * bit 7 bit 0 * Default Configuration after Power-On Reset Legend: R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’ -n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown bit 7 RDY: Ready Bit This bit is the data ready flag. In read mode, this bit indicates if the output register has been updated with a new conversion. In One-Shot Conversion mode, writing this bit to “1” initiates a new conversion. Reading RDY bit with the read command: 1 = Output register has not been updated. 0 = Output register has been updated with the latest conversion data. Writing RDY bit with the write command: Continuous Conversion mode: No effect One-Shot Conversion mode: 1 = Initiate a new conversion. 0 = No effect. bit 6-5 C1-C0: Channel Selection Bits These are the Channel Selection bits, but not used in the MCP3425 device. bit 4 O/C: Conversion Mode Bit 1 = Continuous Conversion Mode. Once this bit is selected, the device performs data conversions continuously. 0 = One-Shot Conversion Mode. The device performs a single conversion and enters a low power standby mode until it receives another write/read command. bit 3-2 S1-S0: Sample Rate Selection Bit 00 = 240 SPS (12 bits), 01 = 60 SPS (14 bits), 10 = 15 SPS (16 bits) bit 1-0 G1-G0: PGA Gain Selector Bits 00 = 1 V/V, 01 = 2 V/V, 10 = 4 V/V, 11 = 8 V/V |
