30 / 40 page  ( ) VrefIO mem_coarse_daca + 1 Rbias ´ DAC3174 SLAS837A – APRIL 2013 – REVISED MAY 2013 www.ti.com Register name: config9 – Address: 0x09, Default: 0x8000 Register Addr Default Bit Name Function Name (Hex) Value config9 0x09 15:13 fifo_ offset This is the starting point for the READ_POINTER in the FIFO block. 100 The READ_POINTER is set to this location when a sync occurs on the AUTO DACCLK side of the FIFO. SYNC 12:0 qmc_ offsetb The DAC B offset correction. The offset is measured in DAC LSBs. 0x0000 NOTE: Writing this register causes an autosync to be generated in the QMOFFSET block. Register name: config10 – Address: 0x0A, Default: 0xF080 Register Addr Default Bit Name Function Name (Hex) Value config10 0x0A 15:12 coarse_ dac Scales the output current is 16 equal steps. 1111 11 fuse_ sleep Put the fuses to sleep when set high. 0 10 reserved reserved 0 9 reserved reserved 0 8 tsense_ sleep When asserted the temperature sensor is put to sleep. 0 7 clkrecv_ ena Turn on the DAC CLOCK receiver block when asserted. 1 6 sleepa When asserted DACA is put to sleep. 0 5 sleepb When asserted DACB is put to sleep. Note: This bit needs to be 0 programmed to "1" for single DAC mode. 4:0 reserved reserved 00000 Register name: config11 – Address: 0x0B, Default: 0x1111 Register Addr Bit Name Function Default Value Name (Hex) config11 0x0B 15:12 reserved reserved 0001 11:8 reserved reserved 0001 7:4 reserved reserved 0001 3:0 reserved reserved 0001 Register name: config12 – Address: 0x0C, Default: 0x3A7A Register Addr Bit Name Function Default Value Name (Hex) config12 0x0C 15:14 reserved reserved 00 13:0 iotest_ pattern0 This is dataword0 in the IO test pattern. It is used with the seven 0x3A7A other words to test the input data. NOTE: This word should be aligned with the rising edge of SYNC when testing the IO interface. Register name: config13 – Address: 0x0D, Default: 0x36B6 Register Addr Bit Name Function Default Value Name (Hex) config13 0x0D 15:14 reserved reserved 00 13:0 iotest_ pattern1 This is dataword1 in the IO test pattern. It is used with the seven 0x36B6 other words to test the input data. 30 Submit Documentation Feedback Copyright © 2013, Texas Instruments Incorporated Product Folder Links :DAC3174 |
