At initial reset, 4,096 Hz is selected.
ENVRST (F75H [D2], W)
This is the reset input to make the duty ratio of the buzzer signal the maximum.
When "1" is written: Reset input
When "0" is written: No operation
Reading: Always "0"
When envelope is added to the buzzer signal, by writing "1" on ENVRST, the envelope is reset and duty
ratio becomes maximum. When envelope is not added, or when buzzer signal is not being output, reset
operation is ineffective.
