S71319-03-000 2/07 TABLE 3-1: Pin Assignments (1 of 3) Symbol Pin No. Pin Type I/O Type Name and Functions 91-TFBGA Host Side Interface A2 K8 I I1Z A[2:0] are used to select one of eight registers in the Task File. A1 K3 A0 L2 D15 H8 I/O I1Z/O2 D[15:0] Data bus D14 G9 D13 G8 D12 H7 D11 F9 D10 F8 D9 E8 D8 F7 D7 F4 D6 H4 D5 E3 D4 H3 D3 F3 D2 G3 D1 F2 D0 G2 DMACK K2 I I2U DMA Acknowledge - input from host DMARQ J3 O O1 DMA Request to host CS1FX# L3 II2Z CS1FX# is the chip select for the task file registers CS3FX# L8 CS3FX# is used to select the alternate status register and the Device Control register. CSEL L9 I I1U This internally pulled-up signal is used to configure this device as a Master or a Slave. When this pin is grounded, this device is configured as a Master. When the pin is open, this device is configured as a Slave. The pin setting should remain the same from Power-on to Power-down. IORD# H2 II2Z This is an I/O Read strobe generated by the host. This signal gates I/O data onto the bus from the chip. IOWR# H9 The I/O Write strobe pulse is used to clock I/O data into the chip. IOCS16# J8 O O2 This output signal is asserted low when the device is indicating a word data transfer cycle. INTRQ J2 O O1 This signal is the active high Interrupt Request to the host. PDIAG# K9 I/O I1U/O1 The Pass Diagnostic signal in the Master/Slave handshake protocol. DASP# D9 I/O I1U/O6 The Drive Active/Slave Present signal in the Master/Slave handshake protocol. RESET# E4 I I2U This input pin is the active low hardware reset from the host. WP_PD# F6 I I1U The WP_PD# pin can be used for either the Write Protect mode or Power-down mode, but only one mode is active at any time. The Write Protect or Power-down modes can be selected through the host command. The Write Protect mode is the factory default setting. |
