How to read circuit diagrams
The circuit diagrams in this chapter are drawn using the same gate symbols as for the 74HCxx
Series standard CMOS logic ICs.
The signal named STOP has a unique function. This signal goes active-high if the CPU sets the
HALT bit when the STBY[1:0] field in the SYSCR2 register is programmed to 01 (i.e., STOP mode)
and the Drive Enable (FRVE) bit in the same register is cleared. If the DRVE bit is set, the STOP
signal remains inactive (at logic 0).
The input protection circuit has a resistor in the range of several tens to several hundreds of ohms.
