Description Pin No.
Pin Name
Type
97 XHPDIAGJ I/O This pin is used as the Passed Diagnostics signal, and may be an input or an open-drain output
92 XHDASPJ I/O
This pin is used as the Drive Active/Slave Present signal, and is an input or an open-drain
output. This pin is used for Master/Slave drive communication and/or for driving an LED
102 XHIORDY I/O
1. I/O channel ready. This signal is driven low to extend host transfer cycles when the controller
is not ready to respond. This pin will be tri-stated when a read or write is not in progress.
2. MPEG error. This pin is used as the ERROR signal when MPEG interface mode is selected
95, 96, 98 XHA[2:0] I
Host address lines. The host address lines A[2:0] are used to access the various host control,
status, and data registers
XHD[15.0] I/O
1. Host data bus. This bus is used to transfer data and status between the host and the controller.
106, 107, 108, 2. MPEG data bus 7-8. The HD[7:0] are used as the DATA [7:0] when MPEG interface mode is selected.
109, 111, 112, 3. VCD I/F. Bit3-0 are used as VCD I/F signal when VCD function is enabled. The relationship of
113, 114, 116, bit3-0 and VCD I/F is as follow
117, 118, 119, HD0—CD-DATA
120, 121, 122, HD1—CD-LRCK
123 HD2—CD-BCK
HD3—CD-C2PO
143 XRSDCLK O This signal is the clock output for SDRAM
147 XROEJ O
This signal is used as the memory output enable for external DRAM buffers. After RSTJ is
asserted, this signal will be low
142 XRWEJ O This signal is asserted low when a buffer memory write operation is active
144 XRRASJ O
This signal is used as Row address output to external DRAM buffer. After RSTJ is asserted, this
signal will be high
145 XRCASJ O
This signal is used as column address output to external DRAM. After RSTJ is asserted, this
signal will be high
1. RAM address lines. These are bits11-0 for addressing the buffer memory.
2. Hardware setting. The bits6-0 are used as hardware setting for some functions.
