Pin Descriptions

The following links refer to descriptions of the pin functions common to the Z85C30 and

Z80C30 devices.

• CTSA, CTSB

• DCDA, DCDB

• DTR/REQA, DTR/REQB

• IEI

• IEO

• INT

• SYNCA, SYNCB

• TxDA, TxDB

• TRxCA, TRxCB

• W/REQA, W/REQB

CTSA, CTSB

Clear To Send (inputs, active Low) .

If these pins are programmed for Auto Enable

functions, a Low on the inputs enables the respective transmitters. If not programmed as

Auto Enable, these pins can be used as general-purpose inputs. Both inputs are Schmitt-

trigger buffered to accommodate slow rise-time inputs. The SCC detects pulses on these

inputs and can interrupt the CPU on both logic level transitions.

DCDA, DCDB

Data Carrier Detect (inputs, active Low) .

These pins function as receiver enables if

programmed for Auto Enable. Otherwise, these pins are used as general-purpose input
