S71193-01-000 9/01 519 For the 40-pin ATA-Disk Module, power can be supplied either through the pin 20 (not present on standard 40-pin IDE interface) or through the external power connector provided on the 40-pin ADM. Please see the drawings in “Physical Dimensions” on page 36 for information. FIGURE 2-1: PIN 30 CONFIGURATION TABLE 2-3: SIGNAL DESCRIPTION Symbol Type1 Pin Name and Functions A2 - A0 I 33,34,35 A[2:0] are used to select one of the Task File registers. D15 - D0 I/O 18,16,14,12,10, 8,6,4,3,5,7,9,11, 13,15,17 Data bus CS1FX#, CS3FX# I 37,38 CS1FX# is the chip select for the task file registers while CS3FX# is used to select the Alternate Status Register and the Device Control Register. CSEL - 28 CSEL signal is a NC to the motherboard. The Master/Slave selection is set by a jumper. If the jumper is in a Master position, the ADM is addressed as a Master drive, and if the jumper is in a Slave position, the ADM is addressed as a Slave drive. IORD# I 25 This is an I/O Read strobe generated by the host. This signal gates I/O data onto the bus from the chip. IOWR# I 23 The I/O Write strobe pulse is used to clock I/O data into the chip. IOCS16# O 32 This output signal is asserted low when this device is expecting a word data transfer cycle. INTRQ O 31 Signal is the active high Interrupt Request to the host. PDIAG# I/O 34 This input/output is the Pass Diagnostic signal in the Master/Slave hand- shake protocol. DASP# I/O 39 This input/output is the Disk Active/Slave present signal in the Master/Slave handshake protocol. RESET# I 1 This input pin is the active low hardware reset from the host. GND - 2,19,22,24,26, 30,40,432 Ground WP#3 I 30 Write protect pin is used to disable Write operation. The 3-position jumper can set pin 30 as NC, write protected (by connecting to GND), or host selectable (by con- necting to pin 30 of IDE connector). When the signal on this pin is low, data on the chip will be write-protected. (See Figure 2-1) VDD -204, 412, 422 Power T2-3.6 519 1. Please refer to Sections 2.3.1 to 2.3.4 for detail 2. Only available with the 44-pin connector module 3. Pin 30 is jumper selectable as NC or WP# 4. Only available with the 40-pin connector module 519 ILL2-5.1 ATA Controller Flash Memory 2 31 Pin 30 WP# Jumper ATA-Disk Module WP# Jumper ATA-Disk Module No Jumper NC, Module is NOT write protected. Close 1, 2 Connect to Ground, Module is write protected Close 2, 3 Host Selectable, Module is write protected if pin 30 is low. Module is NOT write protected if pin 30 is high. T2-3.0 519 |
