EMVSIMx_CTRL field descriptions (continued)
Field Description
0 No DMA Write Request asserted for Transmitter (default)
1 DMA Write Request asserted for Transmitter
19
RX_DMA_EN
Receive DMA Enable
Enables assertion of DMA read request when Receive FIFO reaches the programmed data threshold
value. Request is held asserted till all the programmed threshold bytes are read out. Receiver Data
Interrupt will not be generated when this bit is asserted.
0 No DMA Read Request asserted for Receiver (default)
1 DMA Read Request asserted for Receiver
18
RCVR_11
Receiver 11 ETU Mode Enable
Used to configure the EMV SIM module receiver for 11 ETU operation (that is, 1 Stop bit). This bit is
provided for support of T=1 cards.
0 Receiver configured for 12 ETU operation mode (default)
1 Receiver configured for 11 ETU operation mode
17
XMT_EN
Transmitter Enable
Used to enable/disable the EMV SIM transmitter block. It can be set to 0 during the auto power down
sequence.
Note: Setting this bit (transition from 0 to 1) will reset the CRC and LRC values.
0 EMV SIM Transmitter disabled (default)
1 EMV SIM Transmitter enabled
16
RCV_EN
Receiver Enable
Used to enable/disable the EMV SIM receiver block. Once the transmitter has completed its operation, the
software must enable the receiver using this bit. It can be set to 0 during the auto power down sequence.
0 EMV SIM Receiver disabled (default)
1 EMV SIM Receiver enabled
15–14
Reserved
This field is reserved.
This read-only field is reserved and always has the value 0.
13
STOP_EN
STOP Enable
Used to configure the operation of the EMV SIM module when a processor STOP instruction is executed.
This bit is added to provide support for Smart Cards that do not allow the Smart Card clock to be stopped
while power is applied.
0 STOP instruction shuts down all EMV SIM clocks (default)
1 STOP instruction shuts down all clocks except for the Smart Card Clock (SCK) (clock provided to
Smart Card)
12
DOZE_EN
Doze Enable
Used to configure the operation of the EMV SIM module when a processor DOZE instruction is executed.
0 DOZE instruction will gate all internal EMV SIM clocks as well as the Smart Card clock when the
transmit FIFO is empty (default)
1 DOZE instruction has no effect on EMV SIM module
11
KILL_CLOCKS
Kill all internal clocks
