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 26.12 shows Rising Timing of Transmit Signal.
CRISE2 to CRISE0 = 110b: standard value - 180 μ s
Figure 26.12 Rising Timing of Transmit Signal
The falling timing of the transmit signal is selected by bits CFALL1 to CFALL0 in the CECC4 register.
Figure 26.13 shows Falling Timing of Transmit Signal.
CFALL1 to CFALL0 = 11b: standard value - 160 μ s
10b: standard value - 100 μ s
01b: standard value - 40 μ s
CFALL1 to CFALL0 = 11b: standard value - 310 μ s
10b: standard value - 250 μ s
01b: standard value - 190 μ s
