The addresses of fusemap are 0x400, ...., 0x450, 0x460, 0x470, 0x6D0, etc.
And, only part of 0x450 is accessable by H/W BOOT_CFG pins.
How to access 0x430[21:20] from software or bootloader?
"md" command of u-boot is usable?
I want to read current setting of 0x430[21:20], TAMPER_PIN_DISABLE.
And, I want to change 0x430[21:20]. How can I change it?
