complete flag
During reception, with the error signal output enable bit (bit 7 of address 037D
can output an “L” level from the T
comparing with the case in which the error signal output enable bit (bit 7 of address 037D
signed “0”, the transmission completion interrupt occurs in the half cycle later of the transfer clock.
Therefore parity error signals can be detected by a transmission completion interrupt program. Figure
1.15.25 shows the output timing 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, D
and output from TxD
Figure 1.15.26 shows the SIM interface format.
