CHAPTER 15 UART1
15.4
Interrupt of UART1
The UART1 has a receive and a transmit interrupts, and the following factors can issue
interrupt requests.
• Receive data is loaded to the serial input data register 1 (SIDR1).
• A receive error (parity error, overrun error, framing error) occurs.
• When send data transferred from the output data register 1 (SODR1) to transmit shift
register
Also, each of these interrupt factors supports the expansion intelligent I/O service
(EI
2
OS).
