MultiSynth0 Frequency Increment/Decrement Control.
Bit 4 (disable) must be 0 before writing an increment or decrement
to these bits. Only MS0 can have pin control of Frequency Incre-
ment/Decrement.
0: No frequency inc/dec on MS0
1: Enable pin control of frequency inc/dec
2: Frequency increment on MS0, self-clearing
3: Frequency decrement on MS0, self-clearing
MultiSynth0 Frequency Increment/Decrement Disable (see also
Register 242[1]).
0: Frequency inc/dec enabled on MS0
1: Frequency inc/dec disabled on MS0
MultiSynth0 Spread Spectrum Mode Select.
0: No SSC on MS0
1: Center spread on MS0
2: Reserved
3: Down spread MS0
MultiSynth0 Phase Increment/Decrement Control.
0: No phase inc/dec on MS0
1: Enable pin control of phase inc/dec
2: Phase increment on MS0, self clearing
3: Phase decrement on MS0, self clearing
