ATA5811/ATA5812
The RAM and the status information is stored as long as the transceiver is in any active mode
(DVCC = VS1 or DVCC = V_REG2) and gets lost if the transceiver is in OFF mode
(DVCC = OFF).
After the transceiver is turned on via pin PWR_ON = High, T1 = Low, T2 = Low, T3 = Low,
T4 = Low or T5 = Low or the voltage at pin VAUX V
are in the default state.
