High performance multi-protocol NFC frontend CLRC663 and CLRC663 plus

Bit

Symbol

Description

IFSEL1_EN / OUT5

Enables the output functionality of the IFSEL1 (pin 27). The pin is then used

as output.

IFSEL0_EN / OUT4

Enables the output functionality of the IFSEL0 (pin 26). The pin is then used

as output.

TCK_EN / OUT3

Enables the output functionality of the TCK (pin 4) of the boundary scan

interface. The pin is then used as output. If the boundary scan is activated in

EEPROM, this bit has no function.

TMS_EN / OUT2

Enables the output functionality of the TMS (pin 2) of the boundary scan

interface. The pin is then used as output. If the boundary scan is activated in

EEPROM, this bit has no function.

TDI_EN / OUT1

Enables the output functionality of the TDI (pin 1) of the boundary scan

interface. The pin is then used as output. If the boundary scan is activated in

EEPROM, this bit has no function.

TDO_EN / OUT0

Enables the output functionality of the TDO(pin 3) of the boundary scan

interface. The pin is then used as output. If the boundary scan is activated in

EEPROM, this bit has no function.
