MibADC
The multi-buffered analog-to-digital converter (MibADC) accepts an analog signal and converts the signal to a
10-bit digital value.
The VF3x6A MibADC module can function in two modes: compatibility mode, where its programmer’s model
is compatible with the TMS470R1x ADC module and its digital results are stored in digital result registers; or
in buffered mode, where the digital result registers are replaced with three FIFO buffers, one for each conversion
group [event, group1 (G1), and group2 (G2)]. In buffered mode, the MibADC buffers can be serviced by
interrupts.
MibADC event trigger enhancements
The MibADC includes two major enhancements over the event-triggering capability of the TMS470R1x ADC.
Both group1 and the event group can be configured for event-triggered operation, providing up to two event-
triggered groups.
The trigger source and polarity can be selected individually for both group 1 and the event group from the
three options identified in Table 6.
Table 6. MibADC Event Hookup Configuration
For group 1, these event-triggered selections are configured via the group 1 source select bits (G1SRC[1:0])
in the AD event source register (ADEVTSRC.[5:4]). For the event group, these event-triggered selections are
configured via the event group source select bits (EVSRC[1:0]) in the AD event source register
(ADEVTSRC.[1:0]).
For more detailed functional information on the MibADC, see the TMS470R1x Multi-Buffered Analog-to-Digital
Converter (MibADC) Reference Guide (literature number SPNU206).
