Fig. 11.2.12 Structure of UARTi transmit interrupt control and UARTi receive interrupt control registers
11.2.7 UARTi transmit interrupt control and UARTi receive interrupt control registers
When using UARTi, 2 types of interrupts (UARTi transmit and UARTi receive interrupts) can be used. Each
interrupt has its corresponding interrupt control register. Figure 11.2.12 shows the structure of UARTi
transmit interrupt control and UARTi receive interrupt control registers.
For details about these interrupts, refer to “CHAPTER 6. INTERRUPTS.”
For the UARTi receive interrupt, a receive or receive error interrupt can be selected by the UARTi receive
interrupt mode selected bit (bit 5 at addresses 34
Note: When writing to this bit, use the MOVM (MOVMB) or STA (STAB, STAD) instruction.
