The PIC18F2450/4450 parts you have received

conform functionally to the Device Data Sheet

(DS39760B), except for the anomalies described

below. Any Data Sheet Clarification issues related to

the PIC18F2450/4450 devices will be reported in a

separate Data Sheet errata. Please check the

Microchip web site for any existing issues.

PIC18F2450/4450 devices with these Device/

Revision IDs:

All of the issues listed here will be addressed in future

revisions of the PIC18F2450/4450 silicon.

1. Module: EUSART

The Device IDs (DEVID1 and DEVID2) are located at

addresses

in the format “DEVID2 DEVID1”.

Part Number

PIC18F2450

PIC18F4450

In Synchronous Master mode, while transmitting

the Most Significant data bit, the data line (DT)

may change state before the bit finishes transmit-

ting. If the receiver samples the data line later than

0.5 bit times + 1.5 T

starting edge of the MSb, the bit may be read

incorrectly.

Work around

None.
