The UART is a serial I/O port for asynchronous (start-stop synchronized) or CLK synchronized transmission.
The MB91301 series has three UART channels.
UART Features
• Full duplex double buffer
• Asynchronous (start-stop synchronized) or CLK synchronized transmission
• Supports multi-processor mode
• Fully programmable baud rate
The internal timer can be set to any desired baud rate (see “8. U-TIMER” description)
• Variable baud rate can be input from an external clock.
• Error detection functions (parity, framing, overrun)
• Transmission signal format is NRZ
• The interrupt can be used to initiate DMA transfer.
