Table 17.8 Fast A20 Gate Output Signals
Notes: 1. Arbitrary data with bit 1 set to 1.
17.3.4
Host interface output can be placed in the high-impedance state according to the state of the
HIFSD pin. Setting the SDE bit to 1 in the SYSCR2 register enables the HIFSD pin is slave mode.
The HIF constantly monitors the HIFSD pin, and when this pin goes low, places the host interface
output pins (HIRQ1, HIRQ11, HIRQ12, and GA20) in the high-impedance state. At the same
time, the host interface input pins (CS1, CS2 or ECS2, IOW, IOR, and HA0) are disabled (fixed at
the high input state internally) regardless of the pin states, and the signals of the multiplexed
