Pin Symbol
Function
Name
D7 - D0
Three-state 8-bit bidirectional data bus used when writing control words
and count values, and reading count values upon reception of WR and
RD signals from CPU.
Bidirectional
Data Bus
Input/Output
A0 - A1
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.
Address Input
Input
RD
Data can be transferred from MSM82C53-2 to CPU when this pin is at low
level.
Read Input
Input
WR
Data can be transferred from CPU to MSM82C53-2 when this pin is at low
level.
Write Input
Input
CLK0 - 2
Supply of three clock signals to the three counters incorporated in
MSM82C53-2.
Clock Input
Input
GATE0 - 2
Control of starting, interruption, and restarting of counting in the three
respective counters in accordance with the set control word contents.
Gate Input
Input
OUT0 - 2
Output of counter output waveform in accordance with the set mode and
count value.
Counter Output
Output
CS
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.
