2)
keep the P1, P_CRCA, and DB(15-0) signals negated while continuing to assert and
negate REQ at the negotiated transfer period for the equivalent of 8 transfer periods (e.g.,
50 ns at fast-160);
3)
keep the P1, P_CRCA, DB(15-0), and REQ signals negated for the equivalent of 8
additional transfer periods;
4)
simultaneously assert and negate P1, P_CRCA, and DB(15-0) signals at twice the
negotiated transfer period (i.e., simultaneously repeat a 1100b bit pattern 12 times on
each signal) while asserting and negating REQ at the negotiated transfer period 24 times
(e.g., (2 x 6,25 ns) x 24 = 300 ns at fast-160);
Start of section C:
5)
assert and negate REQ at the negotiated transfer period 64 times and at the same time
assert and negate P1 at twice the negotiated transfer period while repeating a
0000010011111011b bit pattern eight times on each of the P_CRCA and DB(15-0)
signals (e.g., (2 x 6,25 ns) x 64 = 800 ns at fast-160); and
The INIT shall begin its training pattern independent of the start of the TARGs training pattern if
it detects the SEL, MSG, and I/O true and C/D false on the first assertion of the REQ signal. The
INIT shall transmit the following training pattern:
1)
assert ACK signal within 200 ns of the first REQ assertion;
2)
if precompensation is enabled then set the drivers to the strong driver state;
3)
wait the equivalent of 32 transfer periods (e.g., 200 ns at fast-160);
4)
negate ACK signal;
5)
wait the equivalent of 32 transfer periods (e.g., 200 ns at fast-160);
6)
set precompensation to negotiated state; and
7)
assert and negate ACK signal at the negotiated transfer period 32 times, (e.g., (2 x 6,25)
x 32 = 400 ns at fast-160).
At the completion of its training pattern the TARG continues asserting and negating the REQ
signal at the negotiated transfer period (e.g., 6,25 ns transfer period at fast-160) and the P1 signal
at twice the negotiated transfer period (e.g., 12,5 ns transfer period at fast-160). When the TARG
is ready to transfer data it shall reverse the phase of P1.
