UARTx_WP7816 field descriptions
Field Description
WTX Wait Time Multiplier (C7816[TTYPE] = 1)
Used to calculate the value used for the BWT counter. It represents a value between 0 and 255. This
value is used only when C7816[TTYPE] = 1. See Wait time and guard time parameters.
47.3.27 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 any time. This register must be written to only
when C7816[ISO_7816E] is not set.
