Register
The A49FL004 has two registers include the General
Purpose Inputs Register (GPI_REG) and Block Locking
Register (BL_REG). Both registers are available in FWH
and LPC mode only. The GPI_REG can be read at
FFBC0100h in the 4 GByte system memory map. The
BL_REG can be read through FFBx0002h where x=F-0h.
Refer to table 9 for BL_REG.
General Purpose Inputs Register
The A49FL004 contains and 8-bit General Purpose Inputs
Register (GPI_REG) available in FWH and LPC modes.
Only Bit 4 to Bit 0 are used in the current version, and bit 7
to bit 5 are reserved for the future use. The GPI_REG is a
pass-through register with the value set by GPI[4:0] pin
during power-up. The GPI_REG is used for the system
design purpose only, the device does not use this register.
This register is read only and can be read at address
location FFBC0100h in the 4 Gbyte system memory map
through a memory read cycle. Refer to Table 8 for General
Purpose Input Register Definition.

Table 8: General Purpose Inputs Register
Block Locking Registers
The A49FL004 supports block read-lock, write-lock, and
lockdown features through a set of Block Locking Registers.
Each memory block has an associated 8-bit read/writable
block locking register. Only Bit 2 to Bit 0 are used in current
version and Bit 7 to Bit 3 are reserved for future use. The
default value of BL_REG is “01h” at power up. The
definition of BL_REG is listed in Table 8. The FWH/LPC
Register Configuration Map of A49FL004 is shown in Table
9.
