AGC Disable
Description
These bits are reserved and should be written with zeros.
0 = disabled
1 = enabled
A wakeup event is triggered when the PD pin is deasserted and once the IC is ready to receive SPI communications.
Description
These bits are reserved. This register is read-only.
Wakeup status.
0 = Wake interrupt not pending
1 = Wake interrupt pending
This IRQ will assert when a wakeup condition occurs. This bit is cleared by reading the Wake Status register (Reg
0x1D). This register is read-only.

This bit is reserved and should be written with zero.
These bits are reserved and should be written with zeros.
The Power Amplifier Invert bit is used to specify the polarity of the PACTL signal when the PaOe bit is set high.
PA Output Enable and PA Invert cannot be simultaneously changed.
The Reset bit is used to generate a self clearing device reset.
Enabling the Manufacturing ID register (Reg 0x3C-0x3F) consumes power. This bit should only be set when
reading the contents of the Manufacturing ID register (Reg 0x3C-0x3F).
1 = PA Control Output Enabled on PACTL pin.
0 = PA Control Output Disabled on PACTL pin.
1 = PACTL active low
0 = PACTL active high
1 = Device Reset. All registers are restored to their default values.
0 = No Device Reset.
