Note: BUR is undefined after reset, so it must be initialized

to between 1H and 3FH by software.

Note that BUR is a write-only register.

The 6-bit counter is cleared and starts the counting by writ-

ing signal at BUR register. It is incremental from 00H until

it matches 6-bit BUR value.

When main-frequency is 8MHz, buzzer frequency is

shown as below table.
