9.4.2 Carrier Generator Data Registers (CHR1, CLR1, CHR2, and CLR2)
The carrier generator contains one 8-bit data register: primary high time
(CHR1); one 7-bit data register: primary low time (CLR1); and two 6-bit
data registers: secondary high time (CHR2) and secondary low time
(CLR2). Bit 7 of CHR1 and CHR2 is used to read and write the IRO latch.
