Description
0x10
MEMADR
[7:0]
I
00000000
8-bit memory address value for read/write operations.
0x11
MEMDAT
[5:0]
I/O
000000
6-bit memory data value for read/write operations.
0x15
SYNCOUT
[1:0]
O
00
2-bit output value indicates current sync quadrant.
0x16
BYPASS
6
I
0
1: bypasses data synchronization circuitry. Data is sampled using the DAC clock (CLK±)
SYNCEXT
5
I
0
1: enables sync external mode; disable auto quadrant select.
SYNCIN
[4:3]
I
00
2-bit input value is used to specify the sync quadrant.
1 SWRESET also resets itself. SMEM contents are unaffected by SWRESET; however, CALMEM reports an uncalibrated state.
2 EXTREF is optional because the internal reference circuit is designed to be overdriven by an external source.
3 The self-calibration clock is also used for the memory transfer cycle; therefore, the CALCLK value affects the MEMXFER process time.
4 Register Bits 3:0 must all be 0 to assert SELFCAL. The time required for the self-calibration cycle is ~100 ms at 100 MHz with CALCLK = 0.
5 Register Bits 3:0 must all be 0 to assert MEMXFER. The time required for the memory transfer cycle is ~15 ms at 100 MHz with CALCLK = 0.
6 The UNCAL bit remains asserted after the cycle completes (SMEM contents held at default values) until the bit is cleared by the user.
