CH0/1_DMONITORCLK, change adaptaon loop select through DRP, and monitor output
CH0/1_DMONITOROUT. Set aributes DMON_ENABLE, DMON_SRC, DEMONCON, TESTSEL,
and DFELOOPSEL, or FFELOOPSEL via DRP port to enable the digital monitor and select the
appropriate loop for monitoring. The DRP locaons of the aributes are follows.
Channel 0:

• 0x082[2:1]: DMON_SRC
• 0x033[14:12]: DEMONCON
• 0x03B[15]: TESTSEL
• 0x046[15:12]: DFELOOPSEL
• 0x03f[15:12]: FFELOOPSEL
