This mask option can select whether the pull-up resistor
for the I/O port terminal (it works during input mode) is
used or not. It is possible to select for each bit of the I/O
ports. Refer to Chapter 10, "I/O Ports (P Ports)", for
details.
This mask option can select the interface level of the I/O
(P) port from either the CMOS level or CMOS Schmitt
level. It is possible to select for each bit of the I/O ports.
Refer to Chapter 10, "I/O Ports (P Ports)", for details.
This mask option can select whether the built-in reset
voltage detection circuit is used or not. Refer to Section
5.1.2, "Reset voltage detector", for details.
This mask option can select a watchdog timer overflow
cycle. Refer to Chapter 14, "Watchdog Timer", for details.
This mask option can select whether the watchdog timer
overflow signal is used to generate NMI or reset. Refer to
Chapter 14, "Watchdog Timer", for details.
