Data Flow
The data flow between CE and MPU is shown in Figure 26. In a typical application, the 32-bit compute engine (CE) sequen-
tially processes the samples from the voltage inputs on pins IA, VA, IB, and VB, performing calculations to measure active
power (Wh), reactive power (VARh), A
2h, and V2h for four-quadrant metering. These measurements are then accessed by the
MPU, processed further and output using the peripheral devices available to the MPU.

CE/MPU Communication
Figure 27 shows the functional relationship between CE and MPU. The CE is controlled by the MPU via shared registers in the
I/O RAM and by registers in the CE DRAM. The CE outputs two interrupt signals to the MPU: CE_BUSY and XFER_BUSY,
which are connected to the MPU interrupt service inputs as external interrupts. CE_BUSY indicates that the CE is actively
processing data. This signal will occur once every multiplexer cycle. XFER_BUSY indicates that the CE is updating data to the
output region of the CE DRAM. This will occur whenever the CE has finished generating a sum by completing an accumulation
interval determined by SUM_CYCLES * PRE_SAMPS samples. Interrupts to the MPU occur on the falling edges of the
XFER_BUSY and CE_BUSY signals.
