Clarifications/Corrections to the Data

Sheet:

In the Device Data Sheet (DS39760A), the following

clarifications and corrections should be noted. Any

silicon issues related to the PIC18F2450/4450 will be

reported in a separate silicon errata. Please check the

Microchip web site for any existing issues.

1. Module: USB

FIGURE 14-1:

Note:

Configuration

The USB module for this device incorporates con-

figurable, internal pull-up resistors on the D+ and

D- lines. The description and explanation of the

pull-ups, however, have been largely omitted from

the data sheet.

The following additions are made to Section 14.0

“Universal Serial Bus (USB)”:

2. In Section 14.2.2.1 “Internal Transceiver”,

3. A new section is added, following the existing

the following paragraph is added immediately

following the first paragraph:

The on-chip USB pull-up resistors are

controlled by the UPUEN bit (UCFG<4>). They

can only be selected when the on-chip

transceiver is enabled.

Section 14.2.2.2 “External Transceiver”. It

reads in its entirety as follows:

14.2.2.3 Internal Pull-up Resistors

The PIC18F2450/4450 devices have built-in

pull-up resistors designed to meet the require-

ments for low-speed and full-speed USB. The

UPUEN bit (UCFG<4>) enables the internal

pull-ups. Figure 14-1 shows the pull-ups and

their control.

The existing subsections 14.2.2.3 and follow-

ing are renumbered appropriately, starting with

Section 14.2.2.3 “Pull-up Resistors” (now

Section 14.2.2.4).
