Standby Mode
In the standby mode, transmission and reception of signals is deactivated. This is the first step of
reducing the current consumption. The internal voltage regulator control pin (INH) is still active,
so all external (INH controlled) powered devices are also activated.
Wake-Up
The wake-up is possible via WK-pin (filtering time
t
at RxD and switch the transceiver into the normal mode. Once the wake-up flag is set (= LOW),
it remains in this state, as long as the transceiver is not transferred into the normal mode. The
detection of the wake-up source is possible during the first 4 recessive to dominant edges at TxD
in the normal mode.
Go-to Sleep Mode
The go-to sleep mode is used to have an intermediate step between the sleep mode and all other
modes. This mode has to control if the sleep command (EN = 1, NSTB = 0) is activated for a
minimum hold time
mode. The activated features in go-to sleep mode are similar to the standby mode.
Sleep Mode
In the sleep mode, transmission and reception of signals is deactivated. This is the second step of
reducing the current consumption. The internal voltage regulator control pin (INH) is deactivated.
Transition into other Modes during Sleep Mode
Transition from sleep into other modes is possible if
can be done by the mode control inputs.
Wake-Up
The wake-up is possible via WK-pin (filtering time
t
pins to LOW, see
voltage regulator is activated by the inhibit output INH, and the C restarts. Now the C is able
to detect this change at RxD and switch the transceiver into the normal mode. Once the wake-up
flag is set (= LOW), it remains in this state, as long as the transceiver is not transferred into the
normal mode. The detection of the wake-up source is possible during the first 4 recessive to
dominant edges at TxD in the normal mode.
