SUMMARY OF CONFIGURATION WORD WITH FLASH PROGRAM MEMORY

PMCON2: PROGRAM MEMORY CONTROL 2 REGISTER

W-0/0

Program Memory Control Register 2

bit 7

bit 0

Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

S = Bit can only be set

x = Bit is unknown

-n/n = Value at POR and BOR/Value at all other Resets

‘1’ = Bit is set

‘0’ = Bit is cleared

bit 7-0

Flash Memory Unlock Pattern bits

To unlock writes, a 55h must be written first, followed by an AAh, before setting the WR bit of the

PMCON1 register. The value written to this register is used to unlock the writes. There are specific

timing requirements on these writes.
