REGISTER 27-8: CONFIG4H: CONFIGURATION REGISTER 4 HIGH (BYTE ADDRESS 300007h)
U-1 U-1 U-1 U-1 U-0 U-0 R/WO-1 R/WO-1
WPEND WPDIS
bit 7 bit 0
Legend:
R = Readable bit WO = Write-Once 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: Program the corresponding Flash Configuration bit to ‘1
bit 3-2 Unimplemented: Read as ‘0
bit 1 WPEND: Write-Protect Disable bit
1 = Flash pages, WPFP<6:0> to (Configuration Words page), are erase/write-protected
0 = Flash pages 0 to WPFP<6:0> are erase/write-protected
bit 0 WPDIS: Write-Protect Disable bit
1 = WPFP<5:0>, WPEND and WPCFG bits are ignored; all Flash memory may be erased or written
0 = WPFP<5:0>, WPEND and WPCFG bits are enabled; erase/write-protect is active for the selected
region(s)

bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7-5 DEV<2:0>: Device ID bits
These bits are used with DEV<10:3> bits in Device ID Register 2 to identify the part number. See
Register 27-10.
bit 4-0 REV<4:0>: Revision ID bits
These bits are used to indicate the device revision.
