Virtual Flash Page Read
Register
Programming Algorithm
2467M–AVR–11/04
Figure 150. Virtual Flash Page Load Register
The Virtual Flash Page Read Register is a virtual scan chain with length equal to the
number of bits in one Flash page plus 8. Internally the Shift Register is 8-bit, and the
data are automatically transferred from the Flash data page byte by byte. The first eight
cycles are used to transfer the first byte to the internal Shift Register, and the bits that
are shifted out during these 8 cycles should be ignored. Following this initialization, data
are shifted out starting with the LSB of the first instruction in the page and ending with
the MSB of the last instruction in the page. This provides an efficient way to read one full
Flash page to verify programming.
