When the KBC receives data that follows a “D1” command, the hardware control logic sets or clears GATE A20
according to received data bit 1. Similarly, the hardware control logic sets or clears KBRESET depending on
received data bit 0. When the KBC receives an “FE” command, the KBRESET is pulse low for 6 μs (Min.) with a
14 μs (Min.) delay.
GATE A20 and KBRESET are controlled by either software or hardware logic, and they are mutually exclusive.
Then, GATE A20 and KBRESET are merged with Port92 when the P92EN bit is set.
BIT
