7.1 Operating modes
The TJA1041A can be operated in five modes, each with specific features. Control
pins STB and EN select the operating mode. Changing between modes also gives access
to a number of diagnostics flags, available via pin ERR. The following sections describe
the five operating modes.

When go-to-sleep command mode is selected for longer than the minimum hold time of the go-to-sleep
command, the transceiver will enter Sleep mode and pin INH is set floating.
On entering normal mode the pwon flag and the wake-up flag will be cleared.
