13.4 Noise Generator Control
Noise generator is shown in Figure 12-12., which base
frequency is controlled by PSG1L[5~0].
13.5 PSG Noise programming
To program noise generator, PSGO (PMCR[1]) or PSGB
(PMCR[0]) should be set to “1” for PB1 or PB0 in order to be
in PSG output. Noise or DAC function is defined by DACE.
