Summary

Affected Silicon

Revisions

MCAN

10.8 MCAN Data Bit

Timing and Prescaler

On Revision A silicon, the MCAN Data

Bit Timing and Prescaler register

(MCAN_DBTP) is named MCAN Fast

Bit Timing and Prescaler register

(MCAN_FBTP).

MCAN

10.9 MCAN Nominal Bit

Timing and Prescaler

On Revision A silicon, the MCAN

Nominal Bit Timing and Prescaler

Bit Timing and Prescaler register

(MCAN_BTP).

MCAN

10.10 MCAN

Transmitter Delay

Compensation Register

In Revision A silicon, the MCAN

Transmitter Delay Compensation

MCAN

10.11 Timestamping

Function

On Revision A silicon, TC Counter 0 is

not connected to PCK6 and PCK7;

therefore, the timestamping functionality

does not exist.

PIO

11.1 PIO Line

Configuration for AFEC

and DACC Analog

Inputs

To enable the analog inputs, AFE_ADx

or DACx, the pull-up resistors on the I/O

lines must be disabled in the PIO user

interface prior to writing registers

AFEC_CHER or DACC_CHER.

PMC

12.1 Wait Mode Exit

Fail from Flash

The delay to exit from Wait mode is too

short to respect the Flash wake-up time

from Stand-by mode and Deep Power-

down mode. This delay may lead to bad

opcode fetching.

PMC

12.2 PMC_OCR

Reporting

When reading the PMC_OCR register

with the SEL8 and SEL12 bits cleared,

the CAL8 and CAL12 bits are not

updated with the manufacturing

calibration bits of the Main RC Oscillator.

However, the Main RC Oscillator is

loaded with this manufacturing

calibration data.

QSPI

13.1 Module Hangs with

Long DLYCS

The QSPI module hangs if a command

is written to any QSPI register during the

delay defined in the DLYCS bit. There is

no status bit to flag the end of the delay.
