IccBreakDuration: Input parameter
Specifies the break signal duration. Possible values are 0x00 (1 ETU), 0x01 (1.5
ETU) and 0x02 (2 ETU). The default value is 0x00 (1 ETU).
IccRxRetry: Input parameter
The number of retries to allow on reception of a bad byte. Retries = total tries – 1.
IccBreakDetect: Input parameter
Specifies whether to acknowledge (TRUE) or ignore (FALSE) a break coming from
the Smart Card.
IccTxRetry: Input parameter
The number of retries to allow on transmission of a bad byte. Retries = total tries – 1.
IccExtraGuardTime: Input parameter
Specifies the minimum delay in ETUs between the leading edges of two consecutive
characters sent to the Smart Card.
IccBlockGuardTime: Input parameter
Specifies the minimum delay in ETUs between the leading edges of two consecutive
characters sent in opposite directions.
IccCharWaitingTime: Input parameter
Specifies the maximum delay in ETUs between the leading edges of two consecutive
characters from the smart card (T=1 protocol).
IccBlockWaitingTime: Input parameter
Specifies the maximum delay in ETUs between the leading edges of two consecutive
characters sent in opposite directions. Possible values are in the range 0x01
through 0x078000.
IccWorkWaitingTime: Input parameter
Specifies the maximum delay in ETUs between the leading edges of two consecutive
characters from the Smart Card or of one sent to the Smart Card and the next one
received from it (T=0 protocol).
IccPUEnabled: Input parameter
Enables (TRUE) or disables (FALSE) the Smart Card pull-up current source on the
Card Detect pin.
IccPDEnabled: Input parameter
Enables (TRUE) or disables (FALSE) the Smart Card pull-down current source on
the Card Detect pin.
IccVDDFaultOff: Input parameter
When enabled (1), allows the 73S12xxF to automatically perform a deactivation
sequence when there is a VDD Fault. When disabled (0), allows the 73S12xxF to
signal the companion circuit to set its VCC=0 when there is a VDD Fault.
IccAddr: Input parameter
The following settings are defined in API_STRUCT_12.h
IccExtRst: Input parameter
External Reset signal. The following settings are defined in API_STRUCT_12.h:
ICC_INTERNAL – Use this value for slot #1 (Internal slot)
ICC_I2C_0 = 0x40, – Any of these values can be used for I2C, slot # > ICC_1ST
ICC_I2C_1 = 0x42,
ICC_I2C_2 = 0x44,
ICC_I2C_3 = 0x46,
ICC_I2C_4 = 0x48,
ICC_I2C_5 = 0x4A,
ICC_I2C_6 = 0x4C,
ICC_I2C_7 = 0x4E
ICC_NRST = 0x00, – Use this value for slot #1 (Internal slot)
ICC_RST0 = 0x80,
ICC_RST1 = 0x90,
ICC_RST2 = 0xA0,
