Description
Read / Write bit
0 = Read
1 = Write
When reading this register, the R/W bit is 0
Channel Number
00 = LOAD0
01 = LOAD1
10 = LOAD2
Set the KI gain for the PWM period controller
KI = 2^-KI_index. Maximum value = 6. Writing 7 to this field will result
in KI_index=6
KI_index reset value = 010_B
KI reset value = 1/4
Set the PWM period
lsb = 16 / F_SYS
