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