These 4 bits are reserved.
If this bit is set, P3.1 will output the MOUT0 signal.
If this bit is set, P1.4 is configured to be push-pull, and P1.4 will output the system clock.
If this bit is set, P1.5 is configured to be push-pull, and P1.5 will output the digital MLDY
signal of the DTMF generator.
If this bit is set, the TONE output of the DTMF generator is enabled.
