Description
Reserved.
Frequency Divider, F[7:0].
The internal BEEP frequency is the result of dividing the 48kHz clock by 4 times the number specified in
F[7:0].
The lowest tone is 48kHz/(255*4)=47Hz.
The highest tone is 48kHz/(1*4)=12kHz.
A value of 00h in F[7:0] disables the internal BEEP generator and allows external PCBEEP input.

GPIO [3:0] Data.
The value written (output) or sensed (input) on the corresponding pin if it is enabled.
