Not according to DS4119A from Microchip.
For example,=20
18F458-I/P (PDIP) Shows Pin 1 as MCLR/VPP
18F458-I/L (PLCC) Shows Pin 1 as DBGMCLR/VPP and
                                Pin 2 as MCLR/VPP
18F458-I/L (PLCC) Shows Pin 17 as NC. This is the=20
        only NC pin shown for this package in this datasheet
18F458-I/L (PLCC) Shows pin 28 as ICDDATA, there is no comparable
        pin for the PDIP version.
18F458-I/L (PLCC) Shows pin 40 as ICDCLK, There is no comparable
        pin for the PDIP version.

They have apparently separated the ICD connections from the
shared I/O pins, allowing it to be more transparent to the
project being debugged. This is cool for those who use ICD.
I just wondered how best to terminate them if not being used.

Any suggestions would be welcomed.

I am moving a project from  18F458 DIP to PLCC.
The "extra" four pins are marked:

NC
ICDDATA
ICDCLK
DBMCLR/VPP

I can handle the NC, but how (if at all)
should I terminate the other three?

I checked the datasheet, but only found the
purpose for the pins, no info on suggested
termination if they aren't being used.

I am NOT planning any debugger connection,
I just want to place them in a stable,
inactive state.

Any suggestions would be welcomed.
