2.23.3.1 Function for outputting a parity error signal
2.23.3.2 Direct format/inverse format
With the error signal output enable bit (bit 7 of address 037D
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 1.94 shows the output tim-
ing of the parity error signal.
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 1.95 shows the SIM interface format.
Figure 1.96 shows the example of connecting the SIM interface with TxD2 and RxD2.
