9.5 Examples of Macro Service Applications
(1) Serial interface transmission
Each time macro service request (INTST) is generated, the next transmit data is transferred from memory to TXS.
When data n (last byte) has been transferred to TXS (that is, once the transmit data storage buffer becomes
empty), vectored interrupt request (INTST) is generated.
(2) Serial interface reception
Each time macro service request (INTSR) is generated, receive data is transferred from RXB to memory. When
data n (last byte) has been transferred to memory (that is, once the receive data storage buffer becomes full),
vectored interrupt request (INTSR) is generated.
