<Initial setting>
External I/O configuration register
INT_CTR[3:1] (P33/ExINT pin control) = 0012 (RxB_RDY interrupt)
<Operation start>
EXB interrupt source enable register
RXB_ENB (CPU channel receive enable) = “1” (Receive buffer full interrupt enabled)
Writing the command for enabling operation makes RXB_RDY assertion and the P33/ExINT pin goes to “L”.
If the CPU channel receive enable bit (RXB_ENB) is “0”, both the receive buffer full bit (RXB_FULL) and the receive buffer ready signal (RxB_RDY) to an
external are inactive.
When a write operation is performed from an external MCU bus in the condition of ExCS = “L” and WxA0 = “H”, it will result in as follows:
The data is written into the receive buffer (RXBUF)
Negation of the receive buffer ready signal (RxB_RDY) to an external is made
The RXB_FULL interrupt is generated.
When the CPU reads out the receive buffer (RXBUF) with an interrupt processing program, the receive buffer full bit (RXB_FULL) is cleared to “0”.
