Truth Table II – Semaphore Read/Write Control(1)
NOTES:
1. There are eight semaphore flags written to I/O0 and read from all the I/Os (I/O0-I/O35). These eight semaphore flags are addressed by A0-A2.
2. CE = L occurs when CE0 = VIL and CE1 = VIH.
3. Each byte is controlled by the respective BEn. To read data BEn = VIL.
