Parameters
IccId: Input parameter
Specifies which SmartCard UART interface is to be initialized. Possible values are:
ICC_1ST 0 (Internal)
ICC_2ND 1 (External)
…
ICC_9TH
8 (External)
IccDetect: Input parameter
Specifies the detect polarity of the card present. Specify TRUE to detect a card
present when the DET_CARDx pin is HIGH. Specify FALSE to detect a card with
the DET_CARDx pin is LOW. This parameter is only valid for the internal ICC
interface.
IccHz: Input parameter
Specifies the smart card frequency. Possible values are:
ICC_3600KHZ (0)
ICC_1800KHZ (1)
ICC_7200KHZ (2)
The LAPI supports these three rates to follow the same design as the older device
family (73S11xx). The 73S12xxF hardware supports a wider range of smart card
clock generations, which can be derived using a dividing factor (F) such that:
SC clock = 96 MHz / (F + 1) / 2 where F can be any value used to generate the
desired clock. In the three cases above, the F values were defined as: 12, 24 and 6
respectively. See the data sheet for more information.
FiDi: Input parameter
Specifies the current Fi/Di values, equivalent in format to the PPS1 byte of a PPS
request.
IccProtocolT1: Input parameter
Specifies the current protocol, T=1 (TRUE) or T=0 (FALSE). Used to set appropriate
guard and wait times.
IccEDCEnabled: Input parameter
Specifies if the EDC byte(s) are to be updated on the fly.
IccEDCTypeCRC: Input parameter
Specifies if the EDC value is to be calculated with the CRC algorithm (TRUE) or with
the LRC algorithm (FALSE).
IccParityCheck: Input parameter
Specifies if the parity bit is to be checked (TRUE) or not (FALSE).
IccBreakGeneration: Input parameter
Specifies whether the UART must generate a break on a parity error (TRUE) or not
(FALSE).
IccBreakStartPosition: Input parameter
Specifies where the break signal should start. Possible values are 0x00 through 0x07 (in
0.125 ETU increments), which are associated with bit positions 10 through 10.875 ETUs.
For example, 1 corresponds to 10.125 ETUs. The default value is 0x04 (10.5 ETUs).
