UARTx_WP7816A_T1 field descriptions
Field Description
BWI_H Block Wait Time Integer High (C7816[TTYPE] = 1)
Used to calculate the value used for the BWT counter. This register field provides the most significant byte
of the 16 bit Block Wait Time Integer field BWI formed by {WP7816A_T1[BWI_H], WP7816B_T1[BWI_L]}.
The value of BWI = 0 is invalid and should not be programmed. This value is used only when
C7816[TTYPE] = 1. See Wait time and guard time parameters.
47.3.35 UART 7816 Wait Parameter Register B (UARTx_WP7816B_T0)
The WP7816B_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_WP7816B_T0 field descriptions
Field Description
WI_L Wait Time Integer Low (C7816[TTYPE] = 0)
Used to calculate the value used for the WT counter. This register field provides the least 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.
47.3.36 UART 7816 Wait Parameter Register B (UARTx_WP7816B_T1)
The WP7816B_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.
