9.6.2 Soft power-down mode
9.6.3 Standby mode
9.6.4 Automatic receiver power-down
Table 19.
Soft power-down mode is entered immediately using the Control register bit PowerDown.
All internal current sinks, including the oscillator buffer, are switched off. The digital input
buffers are not separated from the input pads and keep their functionality. In addition, the
digital output pins do not change their state.
After resetting the Control register bit PowerDown, the bit indicating Soft power-down
mode is only cleared after 512 clock cycles. Resetting it does not immediately clear it. The
PowerDown bit is automatically cleared when the Soft power-down mode is exited.
Remark: When the internal oscillator is used, time (t
become stable. This is because the internal oscillator is supplied by V
cycles will not be detected by the internal logic until V
The Standby mode is immediately entered when the Control register StandBy bit is set. All
internal current sinks, including the internal digital clock buffer are switched off. However,
the oscillator buffer is not switched off.
The digital input buffers are not separated by the input pads, keeping their functionality
and the digital output pins do not change their state. In addition, the oscillator does not
need time to wake-up.
After resetting the Control register StandBy bit, it takes four clock cycles on pin OSCIN for
Standby mode to exit. Resetting bit StandBy does not immediately clear it. It is
automatically cleared when the Standby mode is exited.
It is a power saving feature to switch off the receiver circuit when it is not needed. Setting
bit RxAutoPD = logic 1, automatically powers down the receiver when it is not in use.
Setting bit RxAutoPD = logic 0, keeps the receiver continuously powered up.
