REGISTER 18-4: PMADRH: PROGRAM MEMORY ADDRESS HIGH BYTE REGISTER
U-0 U-0 U-0 U-0 R/W-0 R/W-0 R/W-0 R/W-0
PMADRH<3:0>
bit 7 bit 0
Legend:
R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-4 Unimplemented: Read as ‘0
bit 3-0 PMADRH<3:0>: Specifies the 4 Most Significant Address bits or High bits for Program Memory Reads.
REGISTER 18-5: PMCON1 – PROGRAM MEMORY CONTROL REGISTER 1
U-1 R/W-0 U-0 U-0 U-0 R/W-0 R/S-0 R/S-0
CALSEL —WRENWR RD
bit 7 bit 0
Legend:
R = Readable bit P = Programmable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 Unimplemented: Read as '1'
bit 6 CALSEL: Program Memory calibration space select
1 = Select test memory area for reads only (for loading calibration trim registers)
0 = Select user area for reads
bit 5-3 Unimplemented: Read as '0'
bit 2 WREN: Program Memory Write Enable bit
1 = Allows write cycles
0 = Inhibits write to the EEPROM
bit 1 WR: Write Control bit
1 = Initiates a write cycle to program memory. (The bit is cleared by hardware when write is complete.
The WR bit can only be set (not cleared) in software.)
0 = Write cycle to the Flash memory is complete
bit 0 RD: Read Control bit
1 = Initiates a program memory read. (The read takes one cycle. The RD is cleared in hardware; the
RD bit can only be set (not cleared) in software).
0 = Does not initiate a Flash memory read
