UART Scratch Pad Register
The UARTx_SPR register can be used by the system as a general-purpose Read/Write reg-
ister. See UART Scratch Pad Registers (UART0_SPR = 00C7h, UART1_SPR = 00D7h).

Description
Delta Status Change of DCD
This bit is set to 1 whenever the DCDx pin changes state. This
bit is reset to 0 when the UARTx_MSR register is read.
Trailing Edge Change on RI
This bit is set to 1 whenever a falling edge is detected on the
RIx pin. This bit is reset to 0 when the UARTx_MSR register is
read.
Delta Status Change of DSR
This bit is set to 1 whenever the DSRx pin changes state. This
bit is reset to 0 when the UARTx_MSR register is read.
Delta Status Change of CTS
This bit is set to 1 whenever the CTSx pin changes state.
This bit is reset to 0 when the UARTx_MSR register is read.
