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 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.
