UART
(1) Description
The UART is a serial I/O port for asynchronous (start-stop) or CLK synchronous communication. This module
has the features listed below.
The MB91F353A/353A/352A/351A contains 4 channels of UART.
The MB91F355A/F356B/F357B/355A/354A/V350A contains 5 channels of UART.
Full duplex double buffer
Asynchronous (start-stop synchronized) or CLK synchronized transmission
Supports multi-processor mode
Completely programmable baud rate.
Arbitrary baud rate set by built-in timer (Refer to the section for "U-timer".)
Variable baud rate can be input from an external clock.
Error detection functions(parity, framing, overrun)
Transmission signal format is NRZ
UART (ch.0 to ch.2) can start DMA transfers using interrupts (ch.3 and ch.4 cannot start DMA transfers).
Capable of clearing DMAC interrupt source by writing to DRCL register
(2) Register list
Serial input register/serial output register (SIDR/SODR)
Serial status register (SSR)
Serial mode register (SMR)
Serial control register (SCR)
DRCL register (DRCL)
