8.5 Application Example of Macro Service
(1) Transfer of serial interface
Each time macro service request INTST is generated, the next transfer data is transferred from memory to TXS. When
data n (last byte) has been transferred to TXS (when the transfer data storage buffer has become empty), vectored interrupt
request INTST is generated.
(2) Reception of serial interface
Each time macro service request INTSR is generated, the receive data is transferred from RXB to memory. When data
n (last byte) has been transferred to memory (when the receive data storage buffer has become full), vectored interrupt
request INTSR is generated.
