NT68F62
PWM DACs (continued)
DAC0 & DAC1 are shared with the ADC2 & ADC3 input pins respectively. If ENADC2/ 3 bit in the ENADC control register is
cleared to LOW, the A/D converters will activate simultaneously. After the chip is reset, ENADC2/ 3 bits will be in HIGH state
and DAC0 & DAC1 will act as PWM output pins.
DAC4 & DAC5 are shared with SCL1 & SDA1 I/O pins respectively. If users clear the ENDDC bit in the CH1CON control
register to LOW, channel 1 of the DDC will be activated. When used as the DDC channel, the I/O port will be of an open
drain structure and include a 'Schmitt Trigger' buffer for noise immunity. After the chip is reset, ENDDC bits will be in HIGH
state and DAC4 - DAC5 will act as PWM output pins.
