Figure 15.33 SIM Interface Connection
Figure 15.34 Parity Error Signal Output Timing
Figure 15.33 shows the SIM Interface Connection. Connect TXD2 and RXD2 and apply pull-up.
15.1.6.1 Parity Error Signal Output
The parity error signal is enabled by setting the U2ERE bit in the U2C1 register to 1 (output enabled).
The parity error signal is output when a parity error is detected while receiving data. This is achieved by
pulling the TXD2 output low with the timing shown in Figure 15.32. If the U2RB register is read while
outputting a parity error signal, the PER bit in the U2RB register is set to 0 (no parity error) and at the
same time the TXD2 output is returned high.
When transmitting, a transmission-finished interrupt request is generated at the falling edge of the transfer
clock pulse that immediately follows the stop bit. Therefore, whether a parity signal has been returned
can be determined by reading the port that shares the UXD2 pin in a transmission-finished interrupt
routine.
