25.3.4 Address Register (FLADR)
FLADR is a 32-bit readable/writable register that specifies the value to be output as an address.
The address of the size specified by ADRCNT[1:0] in the command control register is output
sequentially from ADR1 in byte units. By the sector access address specification bit (ADRMD) of
the command control register, it is possible to specify whether the sector number set in the address
data bits is converted into an address to be output to the flash memory.
When ADRMD = 1
