CHAPTER 4: PERIPHERAL CIRCUITS AND OPERATION (Telephone Function)
4.14.6 Pause
This dialer allows insertion of a pause within 1 to 15 seconds between each two digits of tone signals or
pulses. The pause time should be set to the PTS3–PTS0 register (FF11H) as shown in Table 4.14.6.1 before
dialing.

Do not write "0" (0000B) to the PTS register because it may cause a malfunction.
At initial reset, the pause time is set to 4 seconds.
Writing data to the PTS register just defines the pause time. The actual pause operation will be activated
when the PAUSE bit (FF14HD1) is set to "1".
Figure 4.14.6.1 shows the timing chart of the pause function.
