• Bit 2 - DVDD_OK
This register bit indicates if the internal 1.8V regulated voltage supply DVDD has settled. The bit
is set to logic high, if DVREG_EXT = 1.
Note
• While the reset value of this bit is 0, any practical access to the register is only possible when
DVREG is active. So this bit is normally always read out as 1.
• Bit [1:0] - Reserved
