PWM output to HSADC.Setting this bit to 1'b1, output of PWM channel 1 is routed to HSADC internally.Only
one PWM channle's HSADC_OUT should be set to 1'b1.
If multiple PWM channels are set as HSADC_OUT, only the channel with the lowest channel number will
be routed to HSADC
HSADC clock select for PWM output. Setting this bit to 1'b1, PWM channel 1 counts on HSADC input clock
to drive PWM output.
Multichip Attachment Mode clock select. When the MATT bit is asserted this bit selects which clock to output.
0: 32 kHz, 1: 24 MHz.
