45.3.28 UART 7816 Wait N Register (UARTx_WN7816)
The WN7816 register contains a parameter that is used in the calculation of the guard
time counter. This register may be read at anytime. This register must only be written
when C7816[ISO_7816E] is not set.
Addresses: UART0_WN7816 is 4006_A000h base + 1Ch offset = 4006_A01Ch
UART1_WN7816 is 4006_B000h base + 1Ch offset = 4006_B01Ch
UART2_WN7816 is 4006_C000h base + 1Ch offset = 4006_C01Ch
UART3_WN7816 is 4006_D000h base + 1Ch offset = 4006_D01Ch
UART4_WN7816 is 400E_A000h base + 1Ch offset = 400E_A01Ch
UART5_WN7816 is 400E_B000h base + 1Ch offset = 400E_B01Ch

GTN
Guard Band N
This register field defines a parameter used in the calculation of GT, CGT and BGT counters. The value
represents an integer number 0-255. See Wait time and guard time parameters.
45.3.29 UART 7816 Wait FD Register (UARTx_WF7816)
The WF7816 contains parameters that are used in the generation of various counters
including GT, CGT, BGT, WT and BWT. This register may be read from at anytime.
This register must only be written to when C7816[ISO_7816E] is not set.
