Description
Decoding Type
In PES packet, there is no pointer_field.
GDC21D301A
Values
0 = This packet is a kind of PES.
1 = This packet is a kind of PSI.
Default
Buffer Pointer Register (0x618 ~ 0x61e)
The values are undefined initially. These values are
the memory management registers for local DRAM.
These are 22-bit wide registers only whose 16 bits
can be accessed by the host.
In the following, N = n-2 and n = 3, 4, 5, ..... , 31.
