45.3.26 UART 7816 Wait Parameter Register (UARTx_WP7816T0)
The WP7816 register contains constants used in the generation of various wait timer
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.
Addresses: UART0_WP7816T0 is 4006_A000h base + 1Bh offset = 4006_A01Bh
UART1_WP7816T0 is 4006_B000h base + 1Bh offset = 4006_B01Bh
UART2_WP7816T0 is 4006_C000h base + 1Bh offset = 4006_C01Bh

Wait Timer Interrupt (C7816[TTYPE] = 0)
Used to calculate the value used for the WT counter. It represents a value between 1 and 255. The value
of zero is not valid. This value is used only when C7816[TTYPE] = 0. See . Wait time and guard time

45.3.27 UART 7816 Wait Parameter Register (UARTx_WP7816T1)
The WP7816 register contains constants used in the generation of various wait timer
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.
