clearing VOC[6:0] to ”0000000”. To activate voice output again when returning to normal mode, the
VOC register needs to be set again.

The PWM output volume can be adjusted by command register VOC[6..4]. The bit 6 and 5 control 2
time driver, while bit 4 controls 1 time driver, thus it has 5 levels of driver output. By turning on/off the
internal drivers, the sound level of PWM output can be turned up and down. Please note that this
adjustment apply only to PWM, but not DA output.

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.

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.
