Pin Descriptions
PS005308-0609
The Enhanced Serial Communication Controller (ESCC) pins are divided into seven func-
tional groups:
1. Address/Data
2. Bus Timing and Reset
3. Device Control
4. Interrupt
5. Serial Data (both channels)
6. Peripheral Control (both channels)
7. Clocks (both channels)

both the Z80230 and Z85230/L. The pin functions are unique to each bus interface version
in the Address/Data group, Bus Timing and Reset group, and Device Control group.
The Address/Data group consists of the bidirectional lines used to transfer data between
the CPU and the ESCC (addresses in the Z80230 are latched by AS). The direction of
these lines depends on whether the operation is a Read or a Write operation.
The Timing and Control groups designate the type of transaction to occur and the timing
of the occurrence. The interrupt group provides inputs and outputs for handling and prior-
itizing interrupts. The remaining groups are divided into Channel A and Channel B groups
for:
