Description
Data Bus Input/Output
Address Lines
Chip Enable
Output Enable
Read/Write Enable
Semaphore Enable. When asserted LOW, allows access to eight sema-
phores. The three least significant bits of the address lines will determine
which semaphore to write or read. The I/O
0
pin is used when writing to a
semaphore. Semaphores are requested by writing a 0 into the respective
location.
Interrupt Flag. INT
L
is set when right port writes location 3FFE and is
cleared when left port reads location 3FFE. INT
R
is set when left port writes
location 3FFF and is cleared when right port reads location 3FFF.
