Figure 37. Disable PPG Output by Comparator 1
PPG output is disabled by comparator 1 flag (C1_FLAG) with enable bit DETC1EN in the PPGCR2
register. When DETC1EN is set and comparator 1 output occurs, PPG outputs it's default value.
C1_FLAG is cleared by writing '0'. Once PPG output is disabled by C1_FLAG, C0_FLAG is not
generated until C1_FLAG is cleared.
