R/WL

R/WR

Read/Write Enable

SEML

SEMR

Semaphore Enable. When asserted LOW, allows access to eight semaphores. The three least significant

bits of the address lines will determine which semaphore to write or read. The I/O0 pin is used when writing

to a semaphore. Semaphores are requested by writing a 0 into the respective location.

INTL

INTR

Interrupt Flag. INTL is set when right port writes location 1FFE and is cleared when left port reads location

1FFE. INTR is set when left port writes location 1FFF and is cleared when right port reads location 1FFF.
