Write Protection Registers
To prevent any single software error that may corrupt USART behavior, certain address spaces
can be write-protected by setting the WPEN bit in the USART Write Protect Mode Register
(US_WPMR).
If a write access to the protected registers is detected, then the WPVS flag in the USART Write
Protect Status Register (US_WPSR) is set and the field WPVSRC indicates in which register the
write access has been attempted.
The WPVS flag is reset by writing the USART Write Protect Mode Register (US_WPMR) with
the appropriate access key, WPKEY.
The protected registers are:
•
•
•
•
•
•
•
“USART Mode Register”
“USART Baud Rate Generator Register”
“USART Receiver Time-out Register”
“USART Transmitter Timeguard Register”
“USART FI DI RATIO Register”
“USART IrDA FILTER Register”
“USART Manchester Configuration Register”
