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 V_CC. Mode control is only possible if V_CC of the transceiver is
active.
(3) Pin INH is activated after wake-up via bus input pin WAKE.
(4) Transitions to normal mode clear the internal wake-up: interrupt and battery fail flag are
cleared.
(5) Transitions to sleep mode: pin INH is deactivated.
