• Description: SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
• Manufacturer: Mitsubishi

Clock asynchronous serial I/O (UART) mode
Figure 1.19.22. Output timing of the parity error signal
Figure 1.19.23. SIM interface format
(a) Function for outputting a parity error signal
(b) Direct format/inverse format
With the error signal output enable bit (bit 7 of address 037D
level from the TxD
of a transmission completion interrupt changes to the detection timing of a parity error signal. Figure
1.19.22 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 1.19.23 shows the SIM interface format.
