Mode 10 stands for: Pin STB = HIGH and pin EN = LOW.
(1) Mode change via input pins STB and EN.
(2) Mode change via input pins STB and EN; it should be noted that in the sleep mode pin INH is
inactive and possibly there is no VCC. Mode control is only possible if VCC of the transceiver is
active.
(3) Pin INH is activated and pins RXD and ERR are pulled LOW after wake-up via bus or input
pin WAKE.
(4) Transitions to normal mode clear the internal wake-up: wake-up interrupt flag and power-on flag
are cleared.
(5) Transitions to sleep mode: pin INH is deactivated.
