1.
Set BS1 to “1”. This selects high data byte.
2.
Set XA1, XA0 to “01”. This enables data loading.
3.
Set DATA = Data high byte (0x00 - 0xFF).
4.
Give CLKI a positive pulse. This loads the data byte.
E. No action
F. Repeat B through E until the entire buffer is filled or until all data within the page is loaded.
While the lower bits in the address are mapped to words within the page, the higher bits address
the pages within the FLASH. This is illustrated in Figure 19-2.
Figure 19-2. Addressing the Flash Which is Organized in Pages
Note:
1. PCPAGE and PCWORD are listed in Table 19-8 on page 144.
Note that if less than eight bits are required to address words in the page (pagesize < 256), the
most significant bit(s) in the address low byte are used to address the page when performing a
Page Write.
G. Load Address High byte
1.
Set XA1, XA0 to “00”. This enables address loading.
2.
Set BS1 to “1”. This selects high address.
3.
Set DATA = Address high byte (0x00 - 0xFF).
4.
Give CLKI a positive pulse. This loads the address high byte.
H. Program Page
1.
Give WR a negative pulse. This starts programming of the entire page of data.
RDY/BSY goes low.
2.
Wait until RDY/BSY goes high (See Figure 19-3 on page 149 for signal waveforms).
