Shutdown mode is the lowest power mode and only an external interrupt can wake up the microcontroller.
If an external interrupt source is not available, it is possible to calculate and predict the PWM pulse-centers on an FPGA and send an interrupt to the main processor.
9mm, has a low power drain (together with an external power-down control) and three external interrupt lines, making it a candidate for installation in portable devices requiring applications such as portrait/landscape recognition.
Once a valid external interrupt is recognized by the CPLD, it will determine if it contains the functionality to process the interrupt.
There are also 4 pins that can be configured as chip-select, external interrupt trigger or GIO.
Depending on the power management scheme used, a decrementer interrupt, SMI, or external interrupt (EI) invokes the interrupt handler routine.
In most cases, the processor can correct the condition by utilizing software to remedy the external interrupt.
An external interrupt and built-in comparators linked to the 16-bit timers fulfill hardware requirements for power factor correction (PFC), while NEC Electronics' high-performance 78K0 core--along with the on-board hardware multiplier--tackle the software computation, eliminating the need for a dedicated PFC control IC and thereby reducing system cost and space.
The RCIM includes a synchronized clock readable by multiple systems, up to 8 programmable timers and up to 12 input and 12 output external interrupt lines.
The RCIM includes a synchronized clock, multiple real-time clocks, and input and output external interrupt lines.
