Z85C30/Z80C30 Common Pin Functions
The following sections describe the pin functions common to Z85C30 and
Z80C30 devices:
Each pin function is described below.
CTSA, CTSB
Clear To Send (inputs, active Low) —
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) —
programmed for Auto Enable. Otherwise, these pins are used as general-purpose input
pins. Both pins are Schmitt-trigger buffered to accommodate slow rise-time signals.
The SCC detects pulses on these pins and can interrupt the CPU on both logic level
transitions.
