CRXDEN bit: Bit in the CECC3 register
Bits CRFLG, CRERRFLG, and CRSTFLG: Bits in the CECFLG register
IR bit: Bit in the CEC2IC register
Bits CCRBE and CCRBAI: Bits in the CCRB2 register
The above diagram applies under the following conditions.
y The CFIL bit in the CECC2 register is se to 0 (filter disabled)
y The CABTEN bit in the CECC4 register is set to 1 (error low pulse output enabled)
y The CRISEL2 bit in the CISEL register is set to 1 (receive error interrupt enabled)
y The CRISELS bit in the CISEL register is se to 0 (reception start bit interrupt disabled)
