Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
UART2 Reset Control
When this bit is set, UART module 2 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
UART1 Reset Control
When this bit is set, UART module 1 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
UART0 Reset Control
When this bit is set, UART module 0 is reset. All internal data is lost and
the registers are returned to their reset states. This bit must be manually
cleared after being set.
