Rewrite the G1POCRj register when the BTS bit in the G1BCR1 is 0 (base timer reset), the FSCj bit in
the G1FS register is 0 (waveform generation function selected), and the IFEj bit in the G1FE register is
0 (channel j function disabled). When the G1POCRj register is rewritten, set the BTS bit to 1 after one
or more fBT1 cycles.
MOD1 and MOD0 (Operating mode select bit) (b1-b0)
To select SR waveform output mode, set bits MOD1 and MOD0 of an even channel (channel j (j = 0, 2,
4, or 6)) and bits MOD1 and MOD0 of the next odd channel (channel j + 1) both to 01b. The waveform
is output from the OUT1_j pin of an even channel. In SR waveform output mode, set EOCj + 1 bit in the
G1OER register to 1 (output disabled).
IVL (Output default select bit) (b4)
When a value is written to the IVL bit, the FSCj bit (j = 0 to 7) in the G1FS register is set to 0 (waveform
generation function selected), and the IFEj bit in the G1FE register is set to 1 (channel j function
enabled), the set level is output.
