8.5 Application Example of Macro Service
(1) Serial interface transmission
Each time macro service requests INTST1 and INTST2 are generated, the next transmit data is transferred
from memory to TXS1 and TXS2. When data n (last byte) has been transferred to TXS1 and TXS2 (when the
transmit data storage buffer has become empty), vectored interrupt requests INTST1 and INTST2 are
generated.
(2) Serial interface reception
Each time macro service requests INTSR1 and INTSR2 are generated, the receive data is transferred from
RXB1 and RXB2 to memory. When data n (last byte) has been transferred to memory (when the receive data
storage buffer has become full), vectored interrupt requests INTSR1 and INTSR2 are generated.
