Programming the Flash
The Flash is organized in pages, see
the program data is latched into a page buffer. This allows one page of program data to be pro-
grammed simultaneously. The following procedure describes how to program the entire Flash
memory:
When writing or reading serial data to the ATtiny13A, data is clocked on the rising edge of the
serial clock, see
