Control signal from the processor.
Latched Wake-Up signal
. The bit is set by hardware (or software) and generates a
wake-up interrupt if enabled and the DC/DC STB bit is set. The bit needs to be cleared
by software (SFR and 1 V bits). A SET sequence is required to clear the flag on the 1 V
side. Attention: reading the bit reads the contents of the ‘real’ wake-up flag on the 1 V
side, (read/modify/write commands will fail on this bit).
Test control signal
(uses 76.8 kHz as clock input for high and low counter).
Set operation completed.
Bit set by hardware when the last operation is completed
and the SFRs are again ready to accept new settings. The bit generates a wake-up
interrupt if enabled. The bit needs to be cleared by software.
2 bits that are only reset by a primary RESETIN. The bits can be written to and read
from by the software. The bits are not cleared when the DC/DC converter is switched
off. Same procedure for setting the bits as WU0 to WU15 (reading these bits returns the
‘real’ flags on the 1 V side; read/modify/write commands will fail on this bit).
Load wake-up counter with contents of reload latch
(see Fig.19). Is sampled on the
positive edge of SET.
Clock signal for writing to RUN or wake-up SFR (on 1 V level).
