Description
0 = normal operation of the DRG accumulator (default).
1 = asynchronous, static reset of the DRG accumulator. The ramp accumulator remains reset
as long as this bit remains set. This bit is synchronized with either an I/O_UPDATE or a
PROFILE[2:0] change and the next rising edge of SYNC_CLK.
0 = normal operation of the DDS phase accumulator (default).
1 = asynchronous, static reset of the DDS phase accumulator.
Ineffective unless CFR1[9:8] = 11b.
The output shift keying enable bit.
Ineffective unless CFR1[9] = 1.
This bit is effective without the need for an I/O update.
0 = DAC clock signals and bias circuits are active (default).
1 = DAC clock signals and bias circuits are disabled.
This bit is effective without the need for an I/O update.
0 = auxiliary DAC clock signals and bias circuits are active (default).
1 = auxiliary DAC clock signals and bias circuits are disabled.
0 = assertion of the EXT_PWR_DWN pin affects full power-down (default).
1 = assertion of the EXT_PWR_DWN pin affects fast recovery power-down.
0 = configures the SDIO pin for bidirectional operation; 2-wire serial programming
mode (default).
1 = configures the serial data I/O pin (SDIO) as an input only pin; 3-wire serial
programming mode.
0 = configures the serial I/O port for MSB-first format (default).
1 = configures the serial I/O port for LSB-first format.
0 = OSK disabled (default).
1 = OSK enabled.
0 = manual OSK enabled (default).
1 = automatic OSK enabled.
0 = clock signals to the digital core are active (default).
1 = clock signals to the digital core are disabled.
0 = REFCLK input circuits and PLL are active (default).
1 = REFCLK input circuits and PLL are disabled.
0 = normal operation of the OSK amplitude ramp rate timer (default).
1 = OSK amplitude ramp rate timer reloaded anytime I/O_UPDATE is asserted or a
PROFILE[2:0] change occurs.
