The PIC18FXX8 Rev. B4 parts you have received

conform functionally to the Device Data Sheet

(DS41159D), except for the anomalies described

below.

All of the issues listed here will be addressed in future

revisions of the PIC18FXX8 silicon.

The

PIC18FXX8 devices with these Device/Revision

IDs:

1. Module: ECCP

The Device IDs (DEVID1 and DEVID2) are located at

addresses

in the format “DEVID2 DEVID1”.

PIC18F458

When the ECCP module is operating in Half-

Bridge mode, use of a dead-band delay other than

zero will have the effect of introducing an

unintended pulse on the P1A and P1B signals.

Work around

Disable the dead-band delay by ensuring that the

ECCP1DEL register is set to 00h.
