Figure 16-4. Initialization of Internal Registers Position Register (INITRG)
Read: Anytime
Write: Once in normal and emulation modes and anytime in special modes
This register initializes the position of the internal registers within the on-chip system memory map. The
registers occupy either a 1K byte or 2K byte space and can be mapped to any 2K byte space within the ï¬rst
32K bytes of the systemâs address space.

Description
6:3
Internal Register Map Position â These four bits in combination with the leading zero supplied by bit 7 of
REG[14:11] INITRG determine the upper ï¬ve bits of the base address for the systemâs internal registers (i.e., the minimum
base address is 0x0000 and the maximum is 0x7FFF).
