IDE Timing
The IDE interface supports PIO mode 0-4 as specified in the Information Technology-AT Attachment–4 with Packet Interface Extension
(ATA/ATAPI-4) Specification, T13/1153D Rev 18.
HSS BYTE Mode Transmit
qt_clk, CPU_A, CPUHSS_cs, CPU_wr are internal signals, included in the diagram to illustrate the relationship between CPU opera-
tions and HSS port operations.
Bit 0 is LSB of data byte. Data bits are HIGH true: HSS_TxD HIGH = data bit value ‘1’.
BT = bit time = 1/baud rate.
HSS Block Mode Transmit
BLOCK mode transmit timing is similar to BYTE mode, except the STOP bit time is controlled by the HSS_GAP value.
The BLOCK mode STOP bit time, t
Transmit Gap register [0xC074].
The default t
BT = bit time = 1/baud rate.
HSS BYTE and BLOCK Mode Receive
Receive data arrives asynchronously relative to the internal clock. Incoming data bit rate may deviate from the programmed baud rate
clock by as much as ±5% (with HSS_RATE value of 23 or higher).
BYTE mode received bytes are buffered in a FIFO. The FIFO not empty condition becomes the RxRdy flag.
BLOCK mode received bytes are written directly to the memory system.
Bit 0 is LSB of data byte. Data bits are HIGH true: HSS_RxD HIGH = data bit value ‘1’.
BT = bit time = 1/baud rate.
