3. Module: EUSART

In Asynchronous Receiver mode, the EUSART

does not load the SPBRGHx value after completion

of auto-baud.

Work around

Do not enable the BRG16 (BAUDCONx<3>) bit.

If the BRG16 is in use, ensure that the auto-baud

SPBRGx value does not exceed the 8-bit value.

4. Module: EUSART

The CREN (RCSTAx<4>) bit is cleared after every

auto-baud operation.

Work around

Upon completion of auto-baud, manually set the

CREN bit.

The Device IDs (DEVID1 and DEVID2) are located at

addresses 3FFFFEh:3FFFFFh in the device’s

configuration space. They are shown in hexadecimal

in the format “DEVID2:DEVID1”.

5. Module: A/D

An auto-acquisition A/D conversion requires a

system clock source and can not be used in Sleep

mode. If Sleep mode is entered during an auto-

acquisition period, the A/D conversion will stop

and the device will not wake-up. In addition, upon

wake-up from other source, the result will not be

valid.

Work around

Two work arounds exist:

1. Verify that the A/D conversion has completed

before entering Sleep mode by confirming

either the GO/DONE bit (ADCON0<1>) is ‘0’ or

the ADIF bit (PIR1<6>) is ‘1’.

2. Disable auto-acquisition by clearing the

ACQT2:ACQT0 bits (ADCON2<5:3>) and use

a software delay to acquire the sample.

1. Module: EUSART

If the transmitter is left enabled while the module is

performing an auto-baud operation, an arbitrary

data byte may get transmitted.

Work around

Clear TXEN (TXSTAx<5>) before any auto-baud

operation and set it after auto-baud is complete.

Enable TXEN only when a data byte is to be

transmitted. Care must be taken to ensure that the

TXx pin is pulled high, either through an external

resistor, or by making the TXx pin an output and

writing ‘1’ to it to not disturb the transmit line.

2. Module: EUSART

This module may perform incorrect auto-baud

calculation if the ABDEN (BAUDCONx<0>) bit

was set while the receive pin was at a low level.

Work around

Wait for the RXx pin to go high and then set the

ABDEN bit.
