The host interface registers
BIT Processor’s registers are divided into 2 categories.
Address 0x000 ~ 0x0FC (64 registers address space) are H/W registers. These registers have reset values
and the functions are fixed (not configurable).
Address 0x100 ~ 0x1FC (64 registers) are general purpose S/W registers. They have no reset values and are
configurable by BIT firmware. They are used as interface between host and BIT processor.
Upper 32 registers (address 0x100 ~ 0x17C) are used as static parameters. The meanings or functions of
those registers are not changed for all kinds of run commands (SEQ_INIT, SEQ_END, PICTURE_RUN) and
applied to all commands. Lower 32 registers (address 0x180 ~ 0x1FC) are used as temporal command
arguments. The meanings or functions of those registers may be changed for each run commands.
