11. Module: MSSP (SPI Master Mode)

When the MSSP module is configured as a SPI

master with CKP set, (SPI clock idles high)

disabling the module by clearing the SSPEN bit

will cause the clock line to be driven low for 2 T

OSC

before the setting of the RC3 output in the PORTC

Similarly on enabling the module. There is a 1

OSC period where the clock line will be driven low

before the CKP bit takes effect and the line is

driven high.

Work around

A pull-up resistor on the SCK line allows the pin to

be configured as high-impedance during disabling/

enabling the module and the line to be pulled high

by the resistor.

The TRISC3 bit should be set before disabling or

enabling the module to tristate the pin, and then

cleared before transmission.

12. Module: Capture Compare PWM (CCP)

With the ECCP configured for PWM Half-Bridge

mode and a dead-band delay greater than or equal

to the PWM duty cycle, unpredictable waveforms

will result.

Work around

Make sure the dead-band delay is always less

than the PWM duty cycle.

13. Module: ICSP

If the supply voltage (VDD) applied to the device is

below 2.7V, the device can misread memory

locations while performing an In-Circuit Serial

Programming™ (ICSP™) read or verify command

of the Program Flash Memory (PFM) or the Data

EEPROM. This errata applies to both the High-

Voltage ICSP and the Low-Voltage ICSP modes of

the device, as described in the “PIC16F88X

Memory Programming Specification” (DS41287).

This low-voltage memory misread issue is limited

to only the ICSP hardware interface module on the

device, which is only used during device

programming. In Normal user mode, the device

will operate properly down to the specified V

supply limits, as documented in the device data

sheet (“PIC16F882/883/884/886/887, 28/40/44-

Pin Flash-Based, 8-Bit CMOS Microcontrollers)’’’

(DS41291).

Work around

Maintain a minimum VDD voltage setting of 2.7V or

above when performing an ICSP read or verify

command during programming of the PFM or Data

EEPROM Memory.
