Input UV padding size setting
Should be set by the number of bytes.
Notes: 1. Addition is performed taking that 1 pixel = 1 byte.
2. MCWR (bytes)/2 + MCUVPR (bytes) should be 8 bytes x n (n: an integer greater than
0)
3. MCWR (bytes)/2: Shifts the MCWR setting one bit to the right. (When the setting is odd,
the bit 0 setting is discarded.)
