UARTx_ED field descriptions
Field Description
7
NOISY
The current received dataword contained in D and C3[R8] was received with noise.
0 The dataword was received without noise.
1 The data was received with noise.
6
PARITYE
The current received dataword contained in D and C3[R8] was received with a parity error.
0 The dataword was received without a parity error.
1 The dataword was received with a parity error.
5–0
Reserved
This read-only field is reserved and always has the value zero.
45.3.14 UART Modem Register (UARTx_MODEM)
The MODEM register controls options for setting the modem configuration.
NOTE
RXRTSE, TXRTSPOL, TXRTSE and TXCTSE must all be
cleared when C7816[ISO7816EN] is enabled. This will cause
the RTS to deassert during ISO-7816 wait times. The ISO-7816
protocol does not make use of the RTS and CTS signals.
Addresses: UART0_MODEM is 4006_A000h base + Dh offset = 4006_A00Dh
UART1_MODEM is 4006_B000h base + Dh offset = 4006_B00Dh
UART2_MODEM is 4006_C000h base + Dh offset = 4006_C00Dh
UART3_MODEM is 4006_D000h base + Dh offset = 4006_D00Dh
UART4_MODEM is 400E_A000h base + Dh offset = 400E_A00Dh
UART5_MODEM is 400E_B000h base + Dh offset = 400E_B00Dh

RXRTSE
Receiver request-to-send enable
Allows the RTS output to control the CTS input of the transmitting device to prevent receiver overrun.
NOTE: Do not set both RXRTSE and TXRTSE.
