The PWM output volume can be adjusted by command register PWMC[6..4]. The PWMC[6] and
PWMC[5] control 2 time driver, while PWMC [4] controls 1 time driver, thus it has maximum 5 levels of
driver output. The sound volume of PWM output can be controlled by these PWMC[6..4] bits. Please
note that this adjustment only apply to PWM. When the system enters into sleep mode or idle mode, it
will automatically disable all voice outputs by clearing VOC[6..0] to ”0000000”. To activate voice
output again when returning to normal mode, the VOC register needs to be set again.
