Channel input mapping
Table 21.
Each channel received via I
Channel Input Mapping registers. This allows for flexibility in processing. The default
settings of these registers maps each I
channel.
Configuration register C (addr 0x02)
FFX power output mode
The FFX power output mode selects how the FFX output timing is configured.
Different power devices use different output modes.

S input channel to its corresponding processing
0: processing channel 1 receives left I
1: processing channel 1 receives right I
0: processing channel 2 receives left I
1: processing channel 2 receives right I
Selects configuration of FFX output:
00: drop compensation
01: discrete output stage: tapered compensation
10: full-power mode
11: variable drop compensation (CSZx bits)
When OM[1,0] = 11, this register determines the
size of the FFX compensating pulse from 0 clock
ticks to 15 clock periods.
