SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
1.14.1.6 Port P7
Port P7 is a 5-bit general purpose I/O port that can be
configured to access special second functions.
Port P70
This pin is multiplexed with the USB start of frame
pulse (SOF) output. When USBC6 is a “1”, this pin
outputs the USB SOF.
Port P71
This pin is multiplexed with the HOLD function. When
the MCU is in memory expansion or microprocessor
mode and CPMB5 is set to “1”.
Port P72
This pin is multiplexed with the S1 input control signal
from a Master CPU. When DBBC17 is “1”, the pin
takes on the function of the S1 input control signal.
Port P73
This pin is multiplexed with the IBF1 output control
signal for a Master CPU and the HLDA function.
When DBBC11 and DBBC17 are “1”, the pin takes on
the function of the IBF1 output control signal. When
the MCU is in memory expansion or microprocessor
mode, CPMB5 is set to “1”, and the IBF1 function is
not enabled.
Port P74
This pin is multiplexed with the OBF1 control pin for
the bus interface control block. P74 acts as OBF1 out-
put to a Master CPU when DBBC10 and DBBC17 are
“1”.
