Uart 7816 Atr Duration Timer Register B (Uartx_Ap7816B_T0) - NXP Semiconductors MKL27Z128VFM4 Reference Manual

Memory map and registers
The ADT Counter starts counting on detection of the complete
TS Character. It must be noted that by this time, exactly 10
ETUs have elapsed since the start bit of the TS character. The
user must take this into account while programming this
register.
Address: 4006_C000h base + 3Ah offset = 4006_C03Ah

Field
ADTI_H ATR Duration Time Integer High (C7816[TTYPE] = 0)
Used to calculate the value used for the ADT Counter. This register field provides the most significant byte
of the 16 bit ATR Duration Time Integer field ADTI formed by {AP7816A_T0[ADTI_H],
AP7816B_T0[ADTI_L]}. Programming a value of ADTI = 0 disables the ADT counter. This value is used
only when C7816[TTYPE] = 0. See
38.4.22 UART 7816 ATR Duration Timer Register B
(UARTx_AP7816B_T0)
The AP7816B_T0 register contains variables used in the generation of the ATR Duration
Timer. This register may be read at any time. This register must be written to only when
C7816[ISO_7816E] is not set, except when writing 0 to clear the ADT Counter.
The ADT Counter starts counting on detection of the complete
TS Character. It must be noted that by this time, exactly 10
ETUs have elapsed since the start bit of the TS character. The
user must take this into account while programming this
register.
