I
2C-bus Write to Control Register:
I
2C-bus Write command to the control register follows the format shown below. After the START condition, the
master sends a slave address. This address is seven bits long followed by an eighth bit, which is an opcode bit
(R/
W) – a ‘zero’ indicates the master will write data to the control register. After the R/W bit, the ’zero’ ACK bit is
sent to the master by the device. The master now starts sending the 8 bits of data to the control register during
the DATA bits. After the DATA bits, the ‘zero’ ACK bit is sent to the master by the device. The master should send
the STOP condition after receiving this ACK bit.

Description
PRES
0
Set when the card is present; reset when the card is not present.
PRESL
1
Set when PRES pin changes state (rising/falling edge), reset when the
status register is read. Generates an interrupt when set
I/O
2
Set when I/O is high; reset when I/O is low.
SUPL
3
Set when a voltage fault is detected; reset when the status register is
read. Generates an interrupt when set
PROT
4
Set when an over-current or over-heating fault has occurred during a
card session; reset when the status register is read. Generates an
interrupt when set
MUTE
5
Set during ATR when the card has not answered during the ISO 7816-3
time window (40000 card clock cycles); reset when the next session
begins or this register is read.
EARLY
6
Set during ATR when the card has answered before 400 card clock
cycles; reset when the next session begins or this register is read.
ACTIVE
7
Set when the card is active (VCC is on); reset when the card is inactive
