(7) DC control register 1 (DCCTL1)
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 TO70 to TO75.
DCCTL1 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 TO70 to TO75.
DCCTL1
Symbol
The PWM signal uses the inverter timer output (TO70 to TO75).
2. The PWMCH1, PWMCL1, and INV1 settings are valid only when DCEN1 = 1.
