Table 9.4-1 Explanation of Functions of Each Bit in 12-bit PPG Control Register 1 (RCR21)
Bit name

RCK1, RCK0:
Count clock
selection bits
These bits are used to select a count clock of the 12-bit PPG timer from four types of
internal count clocks.
bit5

bit0
HSC5 to HSC0:
"H" width setting
bits
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 HSC6 to HSC11 bits of the RCR22 register are compared with a
count by the counter.
