Description
Number of dual-purpose LCD/DIO pins to be configured as LCD. This
number can be between 0 and 18. The first dual-purpose pin to be used as
LCD is SEG41/DIO21. If LCD_NUM = 2, SEG41 and SEG 40 will be
configured as LCD. The remaining SEG39 to SEG24 will be configured as
DIO19 to DIO4.

LCD Segment Data. Each word contains information for from 1 to 4 time
divisions of each segment. In each word, bit 0 corresponds to COM0, on up
to bit 3 for COM3.
The MPU clock divider (from CKCE). These bits may be programmed by
the MPU without risk of losing control.
000 - CKCE, 001 - CKCE/2, …, 111 - CKCE/2
MPU_DIV is 000 on power-up.
