I'm using an F28335 micro-controller to implement a PID controller. The internal ADC has a limited resolution (12-bits) so I opted for an external 16-bit ADC, the ADS8361. The ADC data sheet shows a 4-channel sequential mode using a single McBSP channel for the TMS320F28xx (Figure 17 on page 16) and a 4-channel sequential mode using 2 McBSP channels for the TMS320C54xx/C67xx (Figure 16 on page 16). I don't quite understand why I can't use 2 McBSP channels on the F28335 as well. Is figure 16 wrong/incomplete?
