Clarifications/Corrections to the Data

Sheet:

In the Device Data Sheet (DS39626B), the following

clarifications and corrections should be noted. Any

silicon issues related to the PIC18F2525/2620/4525/

4620 devices will be reported in a separate silicon

errata. Please check the Microchip web site for any

existing issues.

1.

Module: I/O Ports

The TRIS setting for the TX pin on PORTC in

Table 10-5 of the Device Data Sheet was incorrectly

stated as ‘1’.

The correct TRIS setting for the TX pin on PORTC

is ‘0’.

2.

Module: Resets

The PR2 initialization condition shown in Table 4-4

for MCLR Resets, WDT Reset, RESET Instruction,

Stack Resets and Wake-up via WDT or Interrupt

should read “uuuu

uuuu

” as shown in the

following table (changes are shown in bold text):

3.

Module: Voltage-Frequency Graph

The title information for Figure 26-2: Voltage-

Frequency Graph (Extended), references the

wrong device family and has been changed to

read as follows:
