Virtual Flash Page
Read Register
2513K–AVR–07/09
Figure 111. 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 eight. Internally the Shift Register is 8-bit, and the data are automati-
cally 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
right 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.
