4. Corruption after receiving too many bits in SPI slave mode
5. USART slave synchronous mode external clock must be at least 9 times lower in fre-
1. In the HMATRIX PRAS and PRBS registers MxPR fields are only two bits
1. Instruction breakpoints affected on all MAC instruction
fer is started and a receive buffer is available, write a one to the RTSEN bit in the USART
CR so that RTS will be driven low.
If the USART is in SPI slave mode and receives too much data bits (ex: 9bitsinstead of 8
bits) by the the SPI master, an error occurs . After that, the next reception may be corrupted
even if the frame is correct and the USART has been disabled, reseted by a soft reset and
re-enabled.
Fix/Workaround
None.
quency than CLK_USART
When the USART is operating in slave synchronous mode with an external clock, the fre-
quency of the signal provided on CLK must be at least 9 times lower than CLK_USART.
Fix/Workaround
When the USART is operating in slave synchronous mode with an external clock, provide a
signal on CLK that has a frequency at least 9 times lower than CLK_USART.
In the HMATRIX PRAS and PRBS registers MxPR fields are only two bits wide, instead of
four bits. The unused bits are undefined when reading the registers.
Fix/Workaround
Mask undefined bits when reading PRAS and PRBS.
Hardware breakpoints on MAC instructions may corrupt the destination register of the MAC
instruction.
Fix/Workaround
Place breakpoints on earlier or later instructions.
