(6) DC control register 0 (DCCTL0)
This register is used to enable/disable PWM modulation, and enable/disable inversion of the output waveform
of the real-time output port.
The output is RTP0 to RTP7.
DCCTL0 is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input clears this register to 00H.
Note
Remarks 1. The output is RTP0 to RTP7.
DCCTL0
Symbol
The PWM signal uses the TO50 output.
2. The PWMCH0, PWMCL0, and INV0 settings are valid only when DCEN0 = 1.
