Description
Reserved
These bits are always read as 0. The write value should
always be 0.
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
23.15 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.
