Receiving data
Data received in the COM port is stored in the receive buffer of MCU, and the “reception done” flag goes
on. When the “reception doen” flag goes on, the data is copied in the operation memory in the CPU
using F161 (MRCV) instruction.
•
Data can be always received in MCU.
•
When detecting the completion of data
reception, the “reception done” flag X0 (X2) of
MCU turns on.
•
When the data reception compl etes, the data
can be copied in the operation memory of the
CPU using the F161 (MRCV) instruction.
•
No end code is included in the stored data.
•
The maximum volume of data t hat can be
received in MCU is 2048 bytes.
