Results: All Table Reads from external blocks to Blockn are disabled whenever EBTRn = ‘0’.
Register Values
TBLPTR = 000FFF
Register Values
TBLPTR = 000FFF
Results: Table Reads permitted within Blockn, even when EBTRBn = ‘0’.
PC = 002FFE
PC = 001FFE
TABLAT register returns a value of “0”.
TABLAT register returns the value of the data at the location TBLPTR.
