Notes:
6. During a break, the watchdog timer
continues to operate.
Therefore, an internal reset is generated if an overflow occurs
during the break.

8.3.1 Overview 213 Description amended
Port 2 is an 8-bit I/O port. Figure 8.2 shows its pin configuration.
In the F-ZTAT version, the on-chip pull-up MOS for pin P2
4
is on
during the reset period. It turns off and normal operation resumes
after the reset is cleared. The pull-up MOS is controlled by
hardware; it cannot be manipulated by a user program. This
should be considered when making connections to external
circuitry. Note that the mask ROM and ZTAT versions do not have
this function.
