UARTx_AP7816B_T0 field descriptions (continued)
Field Description
Used to calculate the value used for the ADT counter. This register field provides the least 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 ATR Duration Time Counter.
47.3.33 UART 7816 Wait Parameter Register A (UARTx_WP7816A_T0)
The WP7816A_T0 register contains constants used in the generation of various wait time
counters. To save register space, this register is used differently when C7816[TTYPE] =
0 and C7816[TTYPE] = 1. This register may be read at any time. This register must be
written to only when C7816[ISO_7816E] is not set.

UARTx_WP7816A_T0 field descriptions
Field Description
WI_H Wait Time Integer High (C7816[TTYPE] = 0)
Used to calculate the value used for the WT counter. This register field provides the most significant byte
of the 16 bit Wait Time Integer field WI formed by {WP7816A_T0[WI_H], WP7816B_T0[WI_L]}. The value
of WI = 0 is invalid and must not be programmed. This value is used only when C7816[TTYPE] = 0. See
Wait time and guard time parameters.
47.3.34 UART 7816 Wait Parameter Register A (UARTx_WP7816A_T1)
The WP7816A_T1 register contains constants used in the generation of various wait time
counters. To save register space, this register is used differently when C7816[TTYPE] =
0 and C7816[TTYPE] = 1. This register may be read at any time. This register must be
written to only when C7816[ISO_7816E] is not set.
