13.1

Overview

The UART is a serial I/O port used to perform asynchronous (start-stop synchronization)
communication or CLK synchronous communication. The MB91260B series has three
UART channels.
■ Features of UART
• Full-duplex double buffer
• Either asynchronous (start-stop synchronization) or CLK synchronous communication can be selected.
• Multiprocessor mode is supported.
• Fully programmable baud rate.
• An arbitrary baud rate can be set using a built-in timer (See "CHAPTER 12 U-TIMER (16-bit Timer
for UART Baud Rate Generation)").
• An external clock can be used to set a baud rate.
• Error detection functions (parity, framing, overrun)
• The transfer signal is an NRZ code.
• DMA transfer cab be started by an interruption.
