Disable/Enable in Interrupts

[sougata]

Hi,

The Enable/Disable are compiler directives which does or does not put the PBP int checking codes into you routine. So this should work. Remember strictly for PBP interrupts. Another way is to turn off the individual interrupt settings only keeping the Global INT turned on i.e., INTCON = $80. If you have other peripheral interrupts then they should be turned off too. (By only clearing the PIE bits perhaps) Mention your PIC and interrupts used.

Thanks for the reply.

The PIC is 16F877 and interrupts are coming from the UART module.

My concern is if the disable directive needs to be inserted in every subroutine. Logicaly not as it is directive and covers all the block of commands until it finds the Enable pair.
