This-8 bit value is passed to sounder controller when key(s)
debounced, if enabled in the configuration register; these 7
bits define duration and frequency only; sounder command
bit D0 is ignored and fixed internally at 1; if a key sound is
sent as 000xxxxx (continuous), then the command is stored
as 111xxxxx (1000 ms)
