Note 1: Read-Modify-Write is prohibited for the registers PCCR, PCFC.
Note 2: When setting PC3-PC0 pins to INT3-INT0 input, set PCDR<PC3D: PC0D> to “0000”(prohibit input), and when driving
PC3-PC0 pins to “0”, execute HALT instruction. This setting generates INT3-INT0 inside. If don’t use external interrupt
in HALT condition, set like an interrupt don’t generated. (e.g. change port setting)
