■ Reading the circuit diagram
Basically, the gate symbols written are the same as those used for the standard CMOS logic
IC [74HCXX] series.
The dedicated signal is described below.
STOP: This signal becomes active “1” when the halt mode setting register is set to the STOP
mode and the CPU executes the HALT instruction. When the drive enable bit <DRVE> is set
to “1”, however, STOP remains at “0”.
The input protection resistance ranges from several tens of ohms to several hundreds of
ohms.
