Virtual Flash Page
Load Register
208
ATmega323(L)
The Virtual Flash Page Load Register is a virtual scan chain with length equal to the
number of bits in one Flash page, 1,024. Internally the Shift Register is 8-bit, and the
data are automatically transferred to the Flash page buffer byte-by-byte. Shift in all
instruction words in the page, starting with the LSB of the instruction with page address
0 and ending with the MSB of the instruction with page address 3F. This provides an
efficient way to load the entire Flash page buffer before executing Page Write.
