– Forced image mode (14)
Only ST7: When the send buffer is 80% full, the TIM switches to the forced image
mode.
To prevent a send buffer overflow, all data frames are treated as image frames. Send
buffer frames are also treated as image frames; the data is overwritten by newer data.
– Locked (15)
The send buffer is locked.
