Circuit Description
The main signals used in LSU Controller are shown in the table.
Name | Direction | Description |
I | The video data output from PVC. | |
|
|
|
nLREADY | I | Its activity becomes low as the polygon motor of LSU gets the regular speed. |
|
|
|
nHSYNC | I | It informs the beginning of one line. It is the same as nLSYNC of PVC. |
|
|
|
nPSync | 0 | It is inputted to nFSync of PVC. |
|
|
|
LSU_VDO | 0 | The completed video data output by masking video window on PVC_VOD. |

12.1.5 ADC Controller
Jupiter4E ADC Controller has 3 analog input channels.
It automatically converts the 3 channels in turns with 10 bit 500KSPS adc1275x_pc, and also it makes the conversion on the desired time by manually controlling STC of the register. After finishing the conversion, it makes the interrup- tion to be pending. When AD conversion of 3 rd channel ends for the PI Control of LSU, it sends the 10bit digital data converted with the latch short pulse signal to LSUC.
