Command FIFO register
Notes: 1.
Setting Method
When accessing this register, the CL_EN bit in GACER should be set to 1. Access is
possible only when the CL_EN bit is set to 1. If the CL_EN bit is 0, access is invalid
(writing is invalid; the result of reading is indefinite).
The following shows the parameter contents assumed according to the writing order:
Writing Order

CL command parameter 4
Output pointer
•
Input Y pointer: Pointer for input Y data (Input Y data storing address)
•
Input U pointer: Pointer for input U data (Input U data storing address)
•
Input V pointer: Pointer for input V data (Input V data storing address)
•
Output pointer: Pointer for output data (Output data storing address)
