#95011 - a question Responding to: ???'s previous message |
After power-up, the slave waits for an OK-to-send (0xAA) signal from the master; the slave sends 0xFF as its first byte and then checks that it actually got the OK-to-send signal before going on.
--- mov a,#0FFh ; load dummy byte call spi_io ; write byte out (waits for sclk in slave mode) --- |
