Parity Control Register (SParCtl): 0xFE11
0x00
This register provides the ability to configure the parity circuitry on the smart card interface. The settings
apply to both integrated smart card interfaces.

SParCtl.7
SParCtl.6
DISPAR
Disable Parity Check – 1 = disabled, 0 = enabled. If enabled, the UART
will check for even parity (the number of 1’s including the parity bit is even)
on every character. This also applies to the TS during ATR.
SParCtl.5
BRKGEN
Break Generation Disable – 1 = disabled, 0 = enabled. If enabled, and T=0
protocol, the UART will generate a Break to the smart card if a parity error
is detected on a receive character. No Break will be generated if parity
checking is disabled. This also applies to TS during ATR.
SParCtl.4
BRKDET
Break Detection Disable – 1 = disabled, 0 = enabled. If enabled, and T=0
protocol, the UART will detect the generation of a Break by the smart card.
SParCtl.3
RETRAN
Retransmit Byte – 1 = enabled, 0 = disabled. If enabled and a Break is
detected from the smart card (Break Detection must be enabled), the last
character will be transmitted again. This bit applies to T=0 protocol.
SParCtl.2
DISCRX
Discard Received Byte – 1 = enabled, 0 = disabled. If enabled and a parity
error is detected (Parity checking must be enabled), the last character
received will be discarded. This bit applies to T=0 protocol.
SParCtl.1
INSPE
Insert Parity Error – 1 = enabled, 0 = disabled. Used for test purposes. If
enabled, the UART will insert a parity error in every character transmitted
by generating odd parity instead of even parity for the character.
SParCtl.0
FORCPE
Force Parity Error – 1 = enabled, 0 = disabled. Used for test purposes. If
enabled, the UART will generate a parity error on a character received from
the smart card.
