Programming the Flash

The Flash is organized in pages, see Table 17-9 on page 108. When programming the Flash,

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:

1. Load Command “Write Flash” (see Table 17-13 on page 111).

2. Load Flash Page Buffer.

3. Load Flash High Address and Program Page. Wait after Instr. 3 until SDO goes high for

the “Page Programming” cycle to finish.

4. Repeat 2 through 3 until the entire Flash is programmed or until all data has been

programmed.

5. End Page Programming by Loading Command “No Operation”.

When writing or reading serial data to the ATtiny13A, data is clocked on the rising edge of the

serial clock, see Figure 17-4 on page 115, Figure 18-5 on page 123 and Table 18-10 on page

123 for details.
