Table 9-51 AVREG_EXT Register Bits
• Bit 6 – AVDD_OK - AVDD Supply Voltage Valid
This register bit indicates if the internal 1.8V regulated voltage supply AVDD has
settled. The bit is set to logic high if AVREG_EXT = 1.
Table 9-52 AVDD_OK Register Bits
• Bit 5:4 – Resx5:4 - Reserved
• Bit 3 – DVREG_EXT - Use External DVDD Regulator
This bit may be set in the Register, but is deactivated in the design. The DVREG_EXT
functionality to deactivate the digital voltage regulator is no implemented anymore
Table 9-53 DVREG_EXT Register Bits
• Bit 2 – DVDD_OK - DVDD Supply Voltage Valid
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.
