PATENA
PATOUT (pattern output) enable
. If PATENA = 1, the pin
PWM9/PATOUT/P3.1 is switched to the PATOUT (display test pattern)
output. If PATENA = 0, the PATOUT function is disabled. The PATOUT
function always overrides other alternative functions such as PWM9 and
P3.1.
DAC outputs enable (n = 3 to 0)
. If DACEn = 1, the corresponding
DACs: DAC3 to DAC0 are enabled. If DACEn = 0, the corresponding
DACs: DAC3 to DAC0 are disabled.
PWM outputs enable; n = 2 to 0
. If PWME2.n = 1, the corresponding
PWMs: PWM8, PWM9 and PWM10, are enabled by PWME2.2,
PWME2.1 and PWME2.0 respectively and pins PWM8/CLAMP/P3.0,
PWM9/PATOUT/P3.1 and PWM10/P1.7 are switched to PWM output. If
PWME2.n = 0, the corresponding PWM is disabled. Pins
PWM8/CLAMP/P3.0, PWM9/PATOUT/P3.1 and PWM10/P1.7 are
switched to I/O port functions P3.0, P3.1 and P1.7 respectively.
