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 maybe read at anytime. This register must only be
written when C7816[ISO_7816E] is not set.
Addresses: UART0_WP7816T1 is 4006_A000h base + 1Bh offset = 4006_A01Bh
UART1_WP7816T1 is 4006_B000h base + 1Bh offset = 4006_B01Bh
UART2_WP7816T1 is 4006_C000h base + 1Bh offset = 4006_C01Bh
UART3_WP7816T1 is 4006_D000h base + 1Bh offset = 4006_D01Bh
UART4_WP7816T1 is 400E_A000h base + 1Bh offset = 400E_A01Bh
UART5_WP7816T1 is 400E_B000h base + 1Bh offset = 400E_B01Bh

UARTx_WP7816T1 field descriptions
Field Description
7–4
CWI
Character Wait Time Integer (C7816[TTYPE] = 1)
This value is used to calculate the value used for the CWT counter. It represents a value between 0 and
15. This value is only used when C7816[TTYPE] = 1. See Wait time and guard time parameters.
3–0
BWI
Block Wait Time Integer(C7816[TTYPE] = 1)
This value is used to calculate the value used for the BWT counter. It represent a value between 0 and
15. This value is only used when C7816[TTYPE] = 1. See Wait time and guard time parameters.
