18. Module: I2C Module (Master Mode)
Under certain circumstances, a module operating
in Master mode may Acknowledge its own com-
mand addressed to a slave device. This happens
when the following occurs:
10-Bit Addressing mode is used (A10M = 1),
and:
the I2C master has the same two upper
address bits (I2CADD<9:8>) as the addressed
slave module.
In these cases, the master also Acknowledges the
address command and generates an erroneous I2C
slave interrupt, as well as the I2C master interrupt.
Work around
Several options are available:
When using 10-Bit Addressing mode, make
certain that the master and slave devices do not
share the same 2 MSBs of their addresses.
If this cannot be avoided:
Clear the A10M bit (I2CxCON<10> = 0) prior to
performing a Master mode transmit.
Read the ADD10 bit (I2CxSTAT<8>) to check
for a full 10-bit match whenever a slave I2C
interrupt occurs on the master module.

19. Module: I2C Module (Slave Mode)
Under certain circumstances, a module operating
in Slave mode may not respond correctly to some
of the special addresses reserved by the I2C
protocol. This happens when the following occurs:
10-Bit Addressing mode is used (A10M = 1),
and
bits, A<7:1>, of the Slave address
(I2CADD<7:1>) fall into the range of the
reserved 7-bit address ranges, ‘1111xxx’ or
‘0000xxx’.
In these cases, the Slave module Acknowledges
the command and triggers an I2C slave interrupt; it
does not copy the data into the I2CxRCV register
or set the RBF bit.
Work around
Do not set bits, A<7:1>, of the module’s slave
address equal to ‘1111xxx’ or ‘0000xxx’.

20. Module: A/D Converter
When using PGEC1 and PGED1 to debug an
application on any 64-pin devices in this family, all
voltage references will be disabled. This includes
VREF+, VREF-, AVDD and AVSS. Any A/D conversion
will always equal 3FFh.
Work around
Use PGEC2 and PGED2 to debug any A/D
functionality.

21. Module: SPIx (Enhanced Buffer Mode)
In Enhanced Master mode, the SRMPT bit
(SPIxSTAT<7>) may erroneously become set for
several clock cycles in the middle of a FIFO transfer,
indicating that the shift register is empty when it is
not. This happens when both SPIx clock prescalers
are set to values other than their maximum
(SPIxCON<4:2> ≠ 000 and SPIxCON<1:0> ≠ 00).
Work around
Configure the module to generate an SPIx event
interrupt whenever the last bit is shifted out of the
shift register (SPIxSTAT<4:2> = 101). When the
SPIxIF flag becomes set, the shift register is
empty.
