The IBF flag bit is inhibited from being cleared until after this point.
Q1
Q1
When in sleep mode the microprocessor may still read and write the Parallel Slave Port. These
actions will set the PSPIF bit. If the PSP interrupts are enabled, this will wake the processor from
sleep mode so that the PSP data latch may be either read, or written with the next value for the
microprocessor.
After any reset the PSP is disabled and PORTD and PORTE are forced to their default mode.
