7.5.3 Data Interpretation
7.5.4 Register Description
8168C-MCU Wireless-02/10
regulators need to be switched off by setting the register bits to the values
AVREG_EXT = 1 and DVREG_EXT = 1. A regulated external supply voltage of 1.8 V
needs to be connected to the pins 13, 14 (DVDD), and pin 29 (AVDD). When turning on
the external supply, ensure a sufficiently long stabilization time before interacting with
the AT86RF212.
The status bits AVDD_OK = 1 and DVDD_OK = 1 of register 0x10 (VREG_CTRL)
indicate an enabled and stable internal supply voltage. Reading value 0 indicates a
disabled voltage regulator or the internal supply voltage is not settled to the final value.
Setting AVREG_EXT = 1 and DVREG_EXT = 1 forces the signals AVDD_OK and
DVDD_OK to 1.
Register 0x10 (VREG_CTRL):
This register controls the use of the voltage regulators and indicates the status of these.
Table 7-17. Register 0x10 (VREG_CTRL)
• Bit 7 – AVREG_EXT
If set, this register bit disables the internal analog voltage regulator to apply an external
regulated 1.8 V supply for the analog building blocks.
Table 7-18. Regulated Voltage Supply Control for Analog Building Blocks
• Bit 6 – AVDD_OK
This register bit indicates if the internal 1.8 V regulated voltage supply AVDD has
settled. The bit is set to logic high if AVREG_EXT = 1.
