• Bit value is undefined when being read.
• Written value does not affect other operations.
These bits are used to set the number of counts corresponding to the "H" width of
12-bit PPG timer outputs (the compare value for the "H" width), and the contents of
these bits and the HSC0 to HSC5 bits of the RCR21 register are compared with a
count by the counter.
