Wake-up selection.
This option defines the wake-up capability. External I/O pins (PA only) all have the capability to wake-up the chip
from a HALT by a falling edge (bit option).
Pull-high selection.
This option is to decide whether the pull-high resistance is visible or not in the input mode of the I/O ports. PA, PB and
PD can be independently selected (bit option).
I/O pins share with other function selections.
PA0/BZ, PA1/BZ: PA0 and PA1 can be set as I/O pins or buzzer outputs.
LCD common selection.
There are three types of selections: 2 common (1/2 duty) or 3 common (1/3 duty) or 4 common (1/4 duty). If the 4
common is selected, the segment output pin SEG40 will be set as a common output.
LCD bias power supply selection.
There are two types of selections: 1/2 bias or 1/3 bias
LCD bias type selection.
This option is to determine what kind of bias is selected, R type or C type.
LCD driver clock frequency selection.

LVD selection.
LVD has enable or disable options
PFD selection.
If PA3 is set as PFD output, there are two types of selections; One is PFD0 as the PFD output, the other is PFD1 as
the PFD output. PFD0, PFD1 are the timer overflow signals of the Timer/Event Counter 0, Timer/Event Counter 1 re-
spectively.
PWM selection: (7+1) or (6+2) mode
PD0: level output or PWM0 output
PD1: level output or PWM1 output
PD2: level output or PWM2 output
PD3: level output or PWM3 output
INT0 or INT1 trigger edge selection: disable; high to low; low to high; low to high or high to low
LCD bias current selection: low/high driving current (for R type only).
