7-Bit DAC/PWM Output:
The 7-bit DAC/PWM voice generator is another scenario and the definitions of PWMC and VOC
registers are different from the 8-bit DAC/PWM format. These registers are different from the 8-bit
architecture and described as following.
The 7-bit voice output is controlled by PWMC and VOC register, and the PWMC is a command/data
register which is determined by PWMC[7] bit. The
VOC
is a three bit voice control register in the 7-bit
mode.
VOC
Field
Reset
PWM: ‘1’ PWM output enabled; ‘0’ PWM output disabled.
DAC: ‘1’ DAC enabled; ‘0’ DAC disabled.
OP: ‘1’ DAC uses DAO pin as output pin; ‘0’ DAC uses VO pin as output pin.

PWME
When users write data into the PWMC register, the PWMC[7] bit will determines the data written into
PWM command register or 7-bit data register and the data register is also sent to the DA converter shown
as the below diagram. The definitions of “PWME” bit and “PWM O/P driver” bits are the same as VOC
register definition of 8-bit output mode.
