Description

Auto-Increment

(during

Read/Write)

0x30

PWMCS

PWM Control and Status register

Yes

0x38

PWMIC0

PWM instructions are initialized through this

data port. Every instruction is 16-bit width and

therefore, the MSB of the first word is written

first, then, followed by LSB of the first word.

Subsequently, MSB of second word and LSB

of second word and so on.

0x39

PWMIC1

PWM instructions are initialized through this

data port. Every instruction is 16-bit width and

therefore, the MSB of the first word is written

first, then, followed by LSB of the first word.

Subsequently, MSB of second word and LSB

of second word and so on.

0x3A

PWMIC2

PWM instructions are initialized through this

data port. Every instruction is 16-bit width and

therefore, the MSB of the first word is written

first, then, followed by LSB of the first word.

Subsequently, MSB of second word and LSB

of second word and so on.
