adjustment
The dead time registers (DTRx/ALTDTRx) must
be modified only when the PWM is not running and
should not be modified “on-the-fly”.
The 16x baud clock signal on the BCLK pin is
present only when the module is transmitting.
When the UART 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.
The SPIxCON1 DISSCK bit does not influence
port functionality.
The BCL bit in I2CSTAT can be cleared only with
16-bit operation and can be corrupted with 1-bit or
8-bit operations on I2CSTAT.

When the I

A9) as other I
work as expected.
The 10-bit slave does not set the RBF flag or load
the I2CxRCV register on an address match if the
Least Significant bits of the address are the same
as the 7-bit reserved addresses.
If the I
with an address of 0x102, the I2CxRCV register
content for the lower address byte is 0x01 rather
than 0x02.
Under certain circumstances, the PERR and
FERR error bits may not be correct for all bytes in
the receive FIFO.
An address error trap occurs in certain addressing
modes when accessing the first four bytes of any
PSV page.
