Preliminary Specification
This is a preliminary specification and is subject to change.
26. Consumer Electronics Control (CEC) Function
26.3.6 Transmission
26.3.6.1 Transmit Signal Timing Select
Rising or falling timing of the transmit signal can be selected.
The rising timing of the transmit signal is selected by bits CRISE2 to CRISE0 in the CECC4 register.
Figure 26.11 shows Rising Timing of Transmit Signal.
CEC output
CRISE2 to CRISE0 = 110b: standard value - 180 ms
101b: standard value - 150 ms
100b: standard value - 120 ms
011b: standard value - 90 ms
010b: standard value - 60 ms
001b: standard value - 30 ms
11b: standard value + 30 ms
000b:
standard value
Figure 26.11 Rising Timing of Transmit Signal
The falling timing of the transmit signal is selected by bits CFALL1 to CFALL0 in the CECC4 register.
Figure 26.12 shows Falling Timing of Transmit Signal.
