ISP Exit Sequence
ISP Byte Sequence
Execute this sequence to exit ISP and resume execution.
Figure 23-25. In-System Programming (ISP) Exit Sequence
Note:
The ISP byte sequence is shown in
Figure 23-26. ISP Byte Sequence
1. Bring SS (P1.4) to “H”.
2. Tri-state MOSI (P1.5).
3. Tri-state SCK (P1.7).
4. Bring RST to “L”.
5. Tri-state SS.
• Data shifts in/out MSB first.
• MISO changes at falling edge of SCK.
• MOSI is sampled at rising edge of SCK.
