The LCD bias mode.
000: 4 states, 1/3 bias
001: 3 states, 1/3 bias
010: 2 states, ½ bias
011: 3 states, ½ bias
100: static display
Controls the number of dual-purpose LCD/DIO pins to be configured
as LCD. LCD_NUM will be between 0 and 18. The first dual-purpose
pin to be allocated as LCD is SEG37/DIO17. The table below lists
which SEG and DIO functions are selected for each LCD_NUM value.
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.
MPU_DIV is 000 on power-up.
The MPU asserts this bit when it wishes the MUX to perform ADC
conversions on an alternate set of inputs.
The number of states in the input multiplexer.
00 - 6 states
MUX_SYNC enable. When high, converts SEG7 into a MUX_SYNC
output.
Tristates the OPT_TX output.
