DOUT BCD code
When dialing, the corresponding 4-bit BCD codes are
serially presented on DOUT from MSB to LSB. The data
of DOUT is valid at the falling edge of the CLOCK pin.
The following table lists the BCD codes corresponding
to the keyboard input.
On hook store (HT9320A/H)
When the external power supply (2V~5.5V) is used and
the HST pin is connected to VDD, the user can store di-
aling numbers to the memories (M1~M20) during
on-hook state.
