(10) Waveform Error Detection<br />

Under development<br />

<strong>TMPM330</strong> (rev0.4)11-22<br />

<strong>TMPM330</strong><br />

To detect an error when a received waveform is out of the defined tolerance range, configure the<br />

CECRCR3 register.<br />

An error is detected when the bit of the CECRCR3 register is enabled. You can<br />

specify the detection time in the bits.<br />

If the rising edge is detected during the period (1) or (2) shown below, or not detected in the timing<br />

described in (3), a waveform error interrupt is generated.<br />

(1) A period between the beginning of a bit and the fastest logical “1” rising timing.<br />

(2) A period between the latest logical “1” rising timing and the fastest logical “0” rising timing.<br />

(3) The latest logical “0” rising timing.<br />
