TMTRSTSp Flags (p = 0 to 31)
These flags indicate the status of the TMTR bit in the RSCAN0TMCp register.
When the TMTR bit is set to 1 (transmission is requested), the corresponding TMTRSTSp flag is set to
1.
The corresponding TMTRSTSp flag is cleared to 0 when the TMTR bit is set to 0 (transmission is not
requested) or in channel reset mode.
Table 21.60 shows the bit assignment.
