■ 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 is set
to “1”, however, STOP remains at “0”.
The input protection resistance ranges from several tens of ohms to several hundreds of
ohms.
