The n is the IxISA device number.
R=Readable W=Writable
Available registers which can be used in structure ixisa_reg for A-8111.
IXISA_AI lets you read this 12-bit register at one fell swoop by three modes - IXISARM_NORMAL
, IXISARM_READY
, and IXISARM_TRIGGER
.
IXISARM_NORMAL mode read register directly. IXISARM_READY mode checks the Ready-bit of high byte and blocks before ADC is ready. IXISARM_TRIGGER mode does software trigger and checks the Ready-bit of high byte.
IXISA_AI is the short term of IXISA_ANALOG_INPUT
Example: ai_soft.c, ai_pacer.c.
