A1 A2 A3 A4 A5
UART IR Mode 1. The 16x baud clock signal on the BCLK pin is present
only when the module is transmitting.
XXXXX
UART High-Speed
Mode
2. When the UARTx is in 4x mode (BRGH = 1) and using
two Stop bits (STSEL = 1), it may sample the first Stop
bit instead of the second one.
XXXXX
SPI Transmit
Operation
3. The SPIx Transmit Buffer Full (SPITBF) flag does not
get set immediately after writing to the buffer.
XXXXX
SPI Frame Mode 4. The SPIx module will generate incorrect frame
synchronization pulses in Frame Master mode if
FRMDLY = 1.
XXXXX
I
2
C™ SFR Writes 5. The BCL bit in I2CxSTAT can only be cleared with
word instructions, and can be corrupted with byte
instructions and bit operations.
XXXXX
I
2
C 10-bit
Addressing
6. When the I
2
C module is configured for 10-bit
addressing, using the same Address bits (A10 and A9)
as other I
2
C devices, A10 and A9 bits may not work as
expected.
XXXXX
I
2
C 10-bit
Addressing
7. When the I
2
C module is configured as a 10-bit slave
with an address of 0x02, the I2CxRCV register content
for the lower address byte is 0x01 rather than 0x02.
XXXXX
I
2
C — 8. With the I
2
C module enabled, the PORT bits and
external interrupt input functions (if any) associated
with SCLx and SDAx pins will not reflect the actual
digital logic levels on the pins.
XXXXX
I
2
C 10-bit
Addressing
9. The 10-bit slave does not set the RBF flag or load the
I2CxRCV register, on address match if the Least
Significant bits (LSbs) of the address are the same as
the 7-bit reserved addresses.
XXXXX
I
2
C — 10. After the ACKSTAT bit is set when receiving a NACK,
it may be cleared by the reception of a Start or Stop
bit.
XXXXX
UART Interrupts 11. The UARTx error interrupt may not occur, or may
occur at an incorrect time, if multiple errors occur
during a short period of time.
XXXXX
UART IR Mode 12. When the UARTx module is operating in 8-bit mode
(PDSEL<1:0> = 0x) and using the IrDA
®
encoder/
decoder (IREN = 1), the module incorrectly transmits
a data payload of 80h as 00h.
XXXXX
Comparator Output Pin 13. When the CxOUTEN (CMCON) bit is set, the
comparator output pin cannot be used as a general
purpose I/O pin, even if the Comparator is disabled.
XXXXX
Internal
Voltage
Regulator
Sleep Mode 14. When the VREGS bit (RCON<8>) is set to a logic ‘0’,
the device may reset and higher Sleep current may be
observed.
XXXXX
PSV
Operations
— 15. An address error trap occurs in certain addressing
modes when accessing the first four bytes of any PSV
page.
XXXXX
Note 1: Only those issues indicated in the last column apply to the current silicon revision.
