(a) Function for outputting a parity error signal
With the error signal output enable bit (bit 7 of address 037D16) assigned “1”, you can output an “L”
level from the TxD2 pin when a parity error is detected. In step with this function, the generation timing
of a transmission completion interrupt changes to the detection timing of a parity error signal. Figure
1.16.23 shows the output timing of the parity error signal.

(b) Direct format/inverse format
Connecting the SIM card allows you to switch between direct format and inverse format. If you choose
the direct format, D0 data is output from TxD2. If you choose the inverse format, D7 data is inverted
and output from TxD2.
Figure 1.16.24 shows the SIM interface format.
