CHAPTER 4 RECEIVING DATA WITH AN INTERRUPT PROGRAM
4
4.4 Programming
● When data reception is performed with an interrupt program, the dedicated BUFRCVS instruction is used regardless of
whether the communication uses the non procedure protocol or bidirectional protocol. For more details on the BUFRCVS
instruction, see Page 371, Section 17.2.
● Create a program that enables/disables interrupts during execution of the main program in order to start the interrupt
program. Use the EI, DI, and IMASK instructions.
