6.5.4 Analog Common Interface Bus

The ACIB links the Master and Control Subsystems with the Analog Subsystem. The ACIB enables the Cortex-M3 CPU/µDMA and C28x CPU/DMA to access Analog Subsystem registers, to send SOC Triggers to the Analog Subsystem, and to receive EOC Interrupts from the Analog Subsystem. The Cortex-M3 uses its System Bus and the µDMA Bus to read from ADC Result registers. The C28x uses its Memory Bus and the DMA bus to access ADC Result registers and other registers of the Analog Subsystem. The ACIB arbitrates between up to four possibly simultaneously occurring bus cycles on the Master/Control Subsystem side of ACIB to access the ADC and Analog Comparator registers on the Analog Subsystem side.

Additionally, ACIB maps up to 22 SOC trigger sources from the Control Subsystem to 8 SOC trigger destinations inside the Analog Subsystem (shared between ADC1 and ADC2), and up to 16 ADC EOC interrupt sources from the Analog Subsystem to 8 destinations inside the Master and Control Subsystems. The eight ADC interrupts are the result of AND-ing of eight EOC interrupts from ADC1 with 8 EOC interrupts from ADC2. The total of 16 possible ADC1 and ADC2 interrupts are sharing the 8 interrupt lines because it is unlikely that any application would need all 16 interrupts at the same time.

Eight registers (TRIG1SEL–TRIG8SEL) configure eight corresponding SOC triggers to assign 1 of 22 possible trigger sources to each SOC trigger.

There are two registers that provide status of ACIB to the Master Subsystem and to the Control Subsystem.

The Cortex-M3 can read the MCIBSTATUS register to verify that the Analog Subsystem is properly powered up; the Analog System Clock (ASYSCLK) is present; and that the bus cycles, triggers, and interrupts are correctly propagating between the Master, Control, and Analog subsystems.

The C28x can read the CCIBSTATUS register to verify that the Analog Subsystem is properly powered up; the Analog System Clock (ASYSCLK) is present; and that the bus cycles, triggers, and interrupts are correctly propagating between the Master, Control, and Analog subsystems.
