Errata History
Errata Descriptions
1.
During UART Reception, Clearing REN May Generate Unexpected IT
During UART reception, if the REN bit is cleared between a start bit detection and
the end of reception, the UART will not discard the data (RI is set).
Workaround
Test REN at the beginning of Interrupt routine just after CLR RI, and run the Inter-
rupt routine code only if REN is set.
2.
SPI Interface - Transmission on Master Mode
A 9th bit is transmitted by the interface when the clock rate is set on divide by 2
mode and a positive polarity is selected; the SPR2, SPR1, SPR0 bits are cleared
(000) and CPOL = 1 on the SPCON register.
Workaround
Set the clock rate divide by 4 and X2 mode.
3.
SPI Interface - SPI SS pin Limitation on Master/Slave
The SS pin of the SPI does not return to an I/O when a One-to-One Master/Slave
intercommunication is performed.
Workaround
No
4.
SPI - SPI Slave Responding in a Multislave Configuration When Not
Selected by the Master and its SPDAT Register Loaded
In a multislave configuration, if the master is sending the Sck and the Tx data to all
the slaves, and only one slave is selected, the non-selected slaves respond and
generate the end of the transmission interruption (SPIF) if their SPDAT registers
are loaded before the transmission.
Workaround
No
