DESCRIPTION

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.
