pins are initialized to the on-chip debugging pin DRST. When using the P911 pin as a port and not as
an on-chip debugging pin, the following handling is required.
<1> Write “0” to OCDM0 bit of OCDM register.
<2> P911/SOB2/[DRST] pin input to “L” until handling <1> above is completed.
Setting DRST = “H” before the above handling is performed when not using on-chip debugging will
cause malfunction (CPU deadlock). Although P911 pin has built-in pull down resister, be careful about
the handling of the P911 pin.
