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.
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 01 - 4 states 10 - 3 states 11 - 2 states
MUX_SYNC enable. When high, converts SEG7 into a MUX_SYNC output.
Tristates the OPT_TX output.
Indicates that the preboot sequence is active.
