Virtual Flash Page Load

The Virtual Flash Page Load Register is a virtual scan chain with length equal to the

number of bits in one Flash page. 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 first instruction in the page and ending

with the MSB of the last instruction in the page. This provides an efficient way to load the

entire Flash page buffer before executing Page Write.
