BIT	FIELD	TYPE	RESET	DESCRIPTION
15	i2c_a0	R/W	0h	When regcommit is used to program an EEPROM page, using regcommit_page, this defines the LSB of the I²C target address. When a configuration is loaded into the registers from an EEPROM page, this represents the saved LSB bit.
14	gpio0_input_sel	R/W	0h	Input signal select for GPIO0, Pin 8. 0h = RESETN 1h = SYNC
13	gpio4_dir_sel	R/W	0h	GPIO4 direction select. 0h = Input 1h = Output
12	gpio1_dir_sel	R/W	0h	GPIO1 direction select. 0h = Input 1h = Output
11	gpio0_dir_sel	R/W	0h	Direction select for Pin 8. 0h = Input 1h = Output
10	zdm_clocksel	R/W	0h	Selects the internal or external clock for calibration, in the ZDM mode. In non-ZDM mode, always internal clock will be selected and this register doesn't have any meaning. 0h = Internal Feedback 1h = External Feedback
9	RESERVED	R/W	0h	RESERVED
8	zdm_mode	R/W	0h	Zero Delay Mode 0h = ZDM Off 1h = ZDM On
7	RESERVED	R/W	0h	RESERVED.
6	pll_rst_lockdet	R/W	0h	Reset (active high) to PLL lock detect circuit.
5	sync	R/WSC	0h	Generates sync pulse (for output decoder). This is a self clearing register bit and writing '1' will create the SYNC pulse.
4	recal	R/WSC	0h	Self clearing bit. Writing '1' will do the re-calibration. For example - after the configuration followed by calibration if '1' is written to this register the calibration engine will start with the current capcode and cross code.
3	resetn_soft	R/W	0h	Configure the pin RESETN/SYNC as a soft reset. 0h = Hard Reset (reset state machines and registers) 1h = Soft Reset (state machines only, register content stays as is)
2	swrst	R/WSC	0h	Soft reset bit. This is a self clearing bit. Writing a '0' has no effect and writing a '1' creates a reset pulse which resets the digital logic except the programmable registers. Also, this soft reset has similar effect on digital logic as hard reset (RESENTN/SYNC). Soft reset will restart the configuration and calibration.
1	powerdown	R/WPD	0h	Analog Power Down. 0h = Active 1h = Power down
0	mode	R/W	0h	Mode of Operation. 0h = Serial Interface, I2C 1h = Pin Mode, Output Enable

8	zdm_auto	R/W	0h	Setting this bit 1 will allow state machine to control the value of pll_ndiv and pll_psfb internally in Normal/ZDM mode of calibration. If set 0 the user has to manually program the pll_ndiv and pll_psfb
7	bypass_cal	R/W	0h	Bypass the calibration. By default two rounds of calibrations (AC followed by FC) will be done. Setting this bit to 1 will bypass the calibration.
6	bypass_config	R/W	0h	Bypass the configuration. Note that on PoR this bit is zero and hence configuration will happen. However after the first configuration this bit can be set and apply the soft/pin reset so that configuration will be bypassed.
5	cal_mute	R/W	1h	Mute the output during the calibration. 0h = Outputs stay active 1h = Outputs muted
4-3	shift_left	R/W	2h	Divide the ref clock (PFD clock) during calibration by 2 to the power of value 0h = 1 1h = 2 2h = 4 3h = 8
