7.25 PWM 2 Pre-Scale Register  Index 82h
Power on default [7:0] = 0000, 0001 b
BIT
NAME
READ/WRITE
DESCRIPTION
7 PWM_CLK_SEL2 Read/Write
PWM 2 Input Clock Select. This bit select PWM 2
input clock.
0: 1 MHz
1: 125 KHz
6-0 PRE_SCALE2[6:0] Read/Write
PWM 2 Input Clock Pre-Scale. The divider of input
clock is the number defined by pre-scale. Thus, writing
0 transfers the input clock directly to counter. The
maximum divider is 128 (7Fh).
00h : divider is 1
01h : divider is 2
02h : divider is 3

7.26 PWM2 Duty Cycle Select Register  Index 83h
Power on default [7:0] = 1111, 1111 b
BIT
NAME
READ/WRITE
DESCRIPTION
7-0 PWM2_DC[7:0] Read/Write
PWM 2 Duty Cycle. This 8-bit register determines the
number of input clock cycles, out of 256-cycle period,
during which the PWM output is high.
00h: PWM output is always logical Low.
FFh: PWM output is always logical High.
XXh: PWM output logical High percentage is
XX/256*100% during one cycle.
7.27 Reserved Register  Index 84h
Power on default [7:0] = 0000, 0000 b
