CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Telephone Function)
DTS: Tone duration time selection (FF16HD2)
Selects the tone duration time. (Mask option)
When "1" is written: 47 msec
When "0" is written: 94 msec
Reading: Valid
When "1" is written to the DTS register, the minimum tone duration time is set to 47 msec and when "0" is
written, it is set to 97 msec.
Note that this register is effective when the DTS function is selected by mask option. If mask option is
selected as "not use", the minimum tone duration time will be fixed at 94 msec.
At initial reset, this resister is set to "0".
TCD0–TCD3: Telephone code for dialing (FF17H)
By writing code to this register, the dialer starts outputting the corresponding dial pulses (in pulse mode)
or tone signals (in tone mode). When the output is finished, an interrupt occurs.
At initial reset, this register is set to "0000B".
The following shows the register settings for each mode.
(1) Pulse mode
In this mode, write data for a dial number (1–9, 0) to this register.
Table 4.14.10.7 lists the relationship of writing codes and pulse counts.

Do not write "0" (0000B) to the TCD register because it may cause a malfunction.
For a dial number between "1" to "9", the number is used for the pulse count as is. Dial number "0"
represents 10 pulses, so write "10" (1010B) to the TCD register.
(2) Tone mode
In this mode, write data for a push button (ROW, COL) to this register.
Table 4.14.10.8 lists the relationship of writing codes and tone frequencies.

Writing data to this register triggers the start of the tone output. When single tone output is selected,
either the ROW frequency or COL frequency corresponding to the written data is output as a tone
signal. When dual tone output is selected, the specified ROW and COL frequencies are output after
they are composed.
