Virtual Flash Page
Read Register
2503Q–AVR–02/11
Figure 142. 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 8 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.
