R/W Description
R/W Output Select 15 to 8
R/W
These bits select the PWM output phase. Bits OS15 to
R/W
OS8 correspond to outputs PW15 to PW8.
R/W
0: PWM direct output (PWDR value corresponds to high
R/W
width of output)
R/W
R/W
1: PWM inverted output (PWDR value corresponds to
R/W
low width of output)
R/W Description
R/W Output Enable 7 to 0
R/W
These bits, together with P1DDR, specify the P1n/PWn
R/W
pin state. Bits OE7 to OE0 correspond to outputs PW7
R/W
to PW0.
