Table 29-36. SCI Pin I/O Control Register 5 (SCIPIO5) Field Descriptions
Bit Field Value Description
31-3 Reserved 0 Reads return 0. Writes have no effect.
2 TX CLR Transmit pin clear. This bit is effective in LIN or SCI mode. This bit clears the logic to be output on pin
LINTX if the following conditions are met:
• TX FUNC = 0 (LINTX pin is a general-purpose I/O.)
• TX DIR = 1 (LINTX pin is a general-purpose output.)
0 Read: The output on LINTX is at logic low (0).
Write: No effect.
1 Read: The output on LINTX is at logic high (1).
Write: The output on LINTX is at logic low (0).
1 RX CLR Receive pin clear. This bit is effective in LIN or SCI mode. This bit clears the logic to be output on pin
LINRX if the following conditions are met:
• RX FUNC = 0 (LINRX pin is a general-purpose I/O.)
• RX DIR = 1 (LINRX pin is a general-purpose output.)
0 Read: The output on LINRX is at logic low (0).
Write: No effect.
1 Read: The output on LINRX is at logic high (1).
Write: The output on LINRX is at logic low (0).
0 Reserved 0 Reads return 0. Writes have no effect.
