PROTECTION_
These bits select a register write protection mode.
00000000 - 10000100, 10000111 - 11111111: Protected mode. No other registers can be written except this register.
10000101: Fully Unprotected mode. All the writable registers can be written. (default)
10000110: Single Unprotected mode. One more register can be written besides this register. After write operation (not
including writing a ‘1’ to clear the bit to ‘0’), the device automatically switches to Protected mode.
