--------------------------------------------------------------
Turning it on
1. Send the value 0x04 to BASE_PORT+2
Turning it off
1. Send the value 0x0C 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
