ZHCSIO0A December 2017 – August 2018 TLC6C5724-Q1
PRODUCTION DATA.
There are eight special command codes defined in the TLC6C5724-Q1 device, shown in Table 21. To input the command, the level of LATCH at the last SCK before the LATCH rising edge must be high, and the highest 12 bits should be one of the listed 8 command codes. In this condition, the device ignores other bits and no data are latched into FC-BC-DC registers. Normally users can write other bits to 0 in the special command. The corresponding command function executes after the rising edge of the LATCH signal.
If no special command code is identified, the command is a NULL command and no special command is executed. The command is the same as the FC-BC-DC write function.
| COMMAND | COMMAND CODE | FUNCTION |
|---|---|---|
| GS read | 5AFh (0101 1010 1111b) | Load GS data into common register. |
| SID read | 5A3h (0101 1010 0011b) | Load SID data into common register. |
| FC-BC-DC read | 5ACh (0101 1010 1100b) | Load FC-BC-DC data into common register. This reading function can also be achieved by GS data write. |
| APS check | 53Ah (0101 0011 1010b) | Adjacent pin short detection, APS test starts at the rising edge of Latch signal, then set APS register(24bits) and APS_Flag in SID register according to the test result. Keep all channels off during this test. |
| LOD_LSD self-test | 535h (0101 0011 0101b) | LOD-LSD detector circuit self test and set LOD_LSD_FLAG in SID register according to the test result. |
| Negate bit toggle | 55Ah (0101 0101 1010b) | Toggle Negate Bit. When Negate Bit = 0, the 48 bits LOD-LSD detector output data will be latched into LOD1-LSD1 and LOD2-LSD2 register without invert. When Negate Bit =1, the 48 bits LOD-LSD detector output data will invert, and latch into LOD1-LSD1 and LOD2-LSD2 register. |
| ERROR clear | A53h (1010 0101 0011b) | Load SID data into common register, and then reset the Error status register and APS register to 0. |
| GLOBAL reset | A5Ch (1010 0101 1100b) | All internal registers are reset. The command has the same function as power on reset. |
| NULL | Different from any of the above commands | The same function as FC-BC-DC write. |
