PIC18F2410/2510/4410/4510

4. Module: 10-Bit Analog-to-Digital

Converter

When the AD clock source is selected as 2 TOSC or

RC (when ADCS<2:0> = 000 or x11), in extremely

rare cases, the EIL (Integral Linearity Error) and

DL (Differential Linearity Error) may exceed the

data sheet specification at codes 511 and 512 only.

Work around

Select the AD clock source as 4 TOSC, 8 TOSC,

16 T

OSC, 32 TOSC or 64 TOSC and avoid selecting

OSC or RC.

Date Codes that pertain to this issue:

All engineering and production devices.

5. Module: MSSP

With MSSP in SPI Master mode, FOSC/64 or

Timer2/2 clock rate, and CKE = 0, a write collision

may occur if SSPBUF is loaded immediately after

the transfer is complete. A delay may be required

after the MSSP Interrupt Flag bit, SSPIF, is set or

the Buffer Full bit, BF, is set and before writing

SSPBUF. If the delay is insufficiently short, a write

collision may occur as indicated by the WCOL bit

being set.

Work around

Add a software delay of one SCK period after

detecting the completed transfer and prior to

updating the SSPBUF contents. Verify the WCOL

bit is clear after writing SSPBUF. If the WCOL is

set, clear the bit in software and rewrite the

SSPBUF register.

Date Codes that pertain to this issue:

All engineering and production devices.

6. Module: Enhanced Capture/Compare/

PWM (ECCP)

With the ECCP configured for Half-Bridge PWM

mode (CCP1M<3:0> = 1110), the output may be

corrupted for particular duty cycle selections.

Affected duty cycle values are 0 though 3, and

every subsequent increment of 4 (i.e., 7, 11, 15,

19, etc.).

Work around

None.

bit 1 WUE: Wake-up Enable bit

Asynchronous mode:

1 = EUSART will continue to sample the RX pin with the interrupt generated on the falling edge; bit

cleared in hardware on following rising edge

0 = RX pin is not monitored or rising edge detected

Synchronous mode:

Unused in this mode.

bit 0 ABDEN: Auto-Baud Detect Enable bit

Asynchronous mode:

1 = Enable baud rate measurement on the next character. Requires reception of a Sync field (55h);

cleared in hardware upon completion.

0 = Baud rate measurement disabled or completed

Synchronous mode:

Unused in this mode.
