Table 9.4-2 Explanation of Functions of Each Bit in 12-bit PPG Control Register 2 (RCR22)

	Bit name		Function
bit7,		Unused bits	• Bit value is undefined when being read.
bit6			• Written value does not affect other operations.
bit5		HSC11 to HSC6:	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
to		"H" width setting
			these bits and the HSC0 to HSC5 bits of the RCR21 register are compared with a
bit0		bits
			count by the counter.
