Since data is being written to buffer registers, the

writing of the first 31 words of the block appears to

occur immediately. The processor will halt internal

operations for the typical 2ms, only during the cycle in

which the erase takes place (i.e., the last word of the

32-word block erase). This is not Sleep mode as the

clocks and peripherals will continue to run. After the 32-

word write cycle, the processor will resume operation

with the third instruction after the PMCON1 write

instruction.
