|
|
1. Send the value 0x04 to BASE_PORT+2

|
Sending a value to the DAC
|
|
|
|
1. Send the unsigned DAC value to the BASE_PORT as normal.
|
|
2. Send the value 0x0C to BASE_PORT+2
|
|
3. Send the value 0x04 to BASE_PORT+2
|
|
--------------------------------------------------------------
|
|
|
|
BASE_PORT + 2 = control port
|
|
0x04 (bit 2) is INIT
|
|
0x0c (bits 2+3) are INIT + nSELECTIN
