Sector Address Specification 
Specify a sector number to be accessed when ADRMD 
= 0. The sector number is converted into an address 
and is output to flash memory. 
When the ADRCNT2 bit in FLCMDCR = 1, the 
ADR[25:0] bits are valid. When the ADRCNT2 bit in 
FLCMDCR = 0, the ADR[17:0] bits are valid. See figure 
25.11 for details. 
  Large-block products (2048 + 64 bytes) 
ADR[25:2] specifies the page address and ADR[1:0] 
specifies the column address in sector units. 
ADR[1:0] = 00: 0th byte (sector 0) 
ADR[1:0] = 01: (512 + 16)th byte (sector 1) 
ADR[1:0] = 00: (1024 + 32)th byte (sector 2) 
ADR[1:0] = 00: (1536 + 48)th byte (sector 3) 
  Small-block products (512 + 16 bytes) 
Only the page address can be specified.
