Input
Three-state 8-bit bidirectional data bus used when writing control
words and count value, and reading count values upon reception of
WR and RD signals from CPU.
CS
Chip Select
Input
Data transfer with the CPU is enabled when this pin is at low level.
When at high level, the data bus (D0 thru D7) is switched to high
impedance state where neither writing nor reading can be executed.
Internal registers, however, remain unchanged.
Data can be transferred from MSM82C54-2 to CPU when this pin is
at low level.
Data can be transferred from CPU to MSM82C54-2 when this pin is
at low level.
One of the three internal counters or the control word register is
selected by A0/A1 combination. These two pins are normally
connected to the two lower order bits of the address bus.
Supply of three clock signals to the three counters incorporated in
MSM82C54-2.
Control of starting, interruption, and restarting of counting in the
three respective counters in accordance with the set control word
contents.
OUT0 - 2
Counter Output
Output
Output of counter output wave form in accordance with the set
mode and count value.
