Wait Time Byte2
Used together with WT[31:24] and WT[15:0] in registers SCWT3,SCWT1,
SCWT0 (see Table 54).
Wait Time Byte 1
Used together with WT[31:16] and WT[7:0] in registers SCWT3,SCWT2, SCWT0
(see Table 51).
Wait Time Byte 0
WT[31:0] is the reload value of the Wait Time counter WTC.
The WTC is a general-purpose timer. It is using the ETU clock and is controlled
by the WTEN bit (see Table 39 on page 45 and Section “Waiting Time (WT)
Counter”, page 40).
When UART bit of Registers is set, the WTC is automatically reloaded at each
start bit of the UART. It is used to check the maximum time between to
consecutive start bits.
