MibADC

The multi-buffered analog-to-digital converter (MibADC) accepts an analog signal and converts the signal

to a 10-bit digital value.

The TMS470M MibADC module stores its digital results in one of three FIFO buffers. There is one FIFO

buffer for each conversion group [event, group1 (G1), and group2 (G2)], and the total MibADC FIFO on

the device is divided amongst these three regions. The size of the individual group buffers are software

programmable. MibADC buffers can be serviced by interrupts.

3.5.1

MIBADC Event Triggers

All three conversion groups can be configured for event-triggered operation, providing up to three

event-triggered groups.

The trigger source and polarity can be selected individually for group 1, group 2 and the event group from

the options identified in Table 3-5.
