Table 19.9
U0TIF, U0TIE, U0RIF, U0RIE: Bits in U0IR register
Note:
Transmit buffer empty
Transmission complete
Reception complete
The UART0 interrupt requests are the transmit buffer empty or transmission complete interrupt, and the reception
complete interrupt. Since these interrupt requests are assigned to a shared vector address, the corresponding source
needs to be determined using the flags.
Table 19.9 lists the Interrupt Requests.
1. The CPU executes interrupt exception handling when the interrupt generation conditions are met and the I flag
Interrupt Request
in the FLG register is 1.
