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 dialing numbers to the memories
(M1~M20) during on-hook state.

Lock function (HT932L)
This function aims to detect lock dialing num-
bers to prevent from an unauthorized long dis-
tance call. The dialing output of this chip is
disabled if the first input key after on-off hook is
the lock number when the lock function is en-
abled.

Hand-free function operation
Hand-free function execution
When HFO is low, a rising edge triggers the
HFI, enabling the Hand-free function (HFO
becomes high).
Reset Hand-free function
When HFO is high, the Hand-free function is
enabled and can be reset by:
Off-hook
Applying a rising edge to HFI
Changing the HDO pin from low to high
