No.
Options
10
Clock source selection of timer/event counter 0. There are two types of selection: system
clock or system clock/4.
11
Clock source selection of timer/event counter 1. There are three types of selection: TMR0
overflow, system clock or Time Base overflow.
12
I/O pins share with other functions selection.
PA0/BZ, PA1/BZ: PA0 and PA1 can be set as I/O pins or buzzer outputs.
PA3/PFD: PA3 can be set as I/O pins or PFD output.
13
LCD common selection. There are three types of selection: 2 common (1/2 duty) or 3 com-
mon (1/3 duty) or 4 common (1/4 duty). If the 4 common is selected, the segment output
pin SEG32 will be set as a common output.
14
LCD bias power supply selection.
There are two types of selection: 1/2 bias or 1/3 bias.
15
LCD bias type selection.
This option is to decide what kind of bias is selected, R type or C type.
16
LCD driver clock selection. There are seven types of frequency signals for the LCD driver
circuits: f
S
/2
2
~f
S
/2
8
. "F
S
" means the clock source selection by options.
17
PFD selection.
If PA3 is set as PFD output, there are two types of selection; One is PFD0 as the PFD out-
put, 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 respectively.
