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 register are 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.

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.
