6.2.2. Bank Address Mapping
The flash controller supports boot sector flash memory and the system always boots from bank0. The
boot bank (bank 0) is mapped to KSEG1 with the start physical address of 0x1E00.0000 (virtual address:
0xBD00.0000). Bank0 is also mapped to the start physical address of 0x1FC0.0000.
The system always boots up from bank 0. For software, it is suggested that the program jumps to the
space [0x1E00.0000~0x1EFF.FFFF] for a larger continuous space after booting up from 0x1FC0.0000.
However, for backward compatibility, the program can choose to stay in the 4MByte space
[0x1FC0.0000~0x1FFF.FFFF].

CO E CO 6.2.3. Flash Command Sequence
ZT Directly write or read the target Flash address following the command sequence specified in the flash
for memory provider’s datasheet. However, programmers must pay attention to the following:
• Use 16-bit (half-word) manipulation. Byte or full word manipulation will cause unpredictable errors
• The Program address is the address defined for the Flash
• The Command address is 0xBFC0.0000 + command address * 2
• Program data/Command data. The data may be placed in either the lower half-word or upper half-
word position in a 32-bit full word. It depends on the least significant two bits of the accessed address
