6.20.2 Dual Tone Control Register (DTCR)
Dual tone control register is organized as 4-bit binary register. The output of the dual or single tone
will be controlled by this register. The MOV DTCR,#I instruction can specify the wanted status. The bit
descriptions are as follows:

DTCR
Bit 0 = 1 Low group tone output is enabled.
Bit 1 = 1 High group tone output is enabled.
Bit 2 = 1 DTMF output is enabled. When Bit 2 is reset to 0, the DTMF output pin will be Hi-Z
state.
Bit 3 is reserved.
6.21 MFP Output Pin (MFP)
The MFP output pin can output the Timer 1 clock or the modulation frequency; the output of the pin is
determined by bit 0 of BUZCR (BUZCR.0). The organization of MR1 is shown in Figure 6-7. When
bit 0 of BUZCR is reset to "0," the MFP output can deliver a modulation output in any combination of
one signal from among DC, 4096 Hz, 2048 Hz, and one or more signals from among 128 Hz, 64 Hz,
8 Hz, 4 Hz, 2 Hz, or 1 Hz (when using a 32.768 KHz crystal). The MOV MFP, #I instruction is used to
specify the modulation output combination. The data specified by the 8-bit operand and the MFP
output pin are shown in next page.
