PCI CLK no (Parallel Port already placed in the reverse ECP transfer mode)
2
- Start of 1
st
ECP reverse transfer by peripheral
2-3
- Peripheral asserts ACK_N low
6
- Host responds by asserting AFD_N (3 clock cycles after sampling ACK_N low)
10-11
- Peripheral deasserts ACK_N
13
- Host responds by de-asserting AFD_N (2 clock cycles after sampling ACK_N low)
- End of ECP reverse transfer (data already transferred to ECP DFIFO)
24
- Start of PCI read fromECP DFIFO (does not initiate or affect any ECP reverse transfers that may be taking place)
26
- Start of 2nd ECP reverse transfer by peripheral.
Tafd (PCI clk to AFD_N valid) : 16ns max*
Tack-afd : 3 clock cycles (see below) + Tafd
ECP Reverse Transfer Cycle duration is dependant upon the timng response of the peripheral’s ACK_N line and the parallel
port filters.Example waveformhas the parallel port filters disabled. An extra 2 PCI CLK cycles will be incurred in the response of
the host to the peripheral’s ACK_N line when the filters are enabled.
