programmable acquisition and control timer (PACT) module
Traditionally, timers in microcontrollers provide limited capture and compare functions consuming significant
CPU processing power and leading to inaccurate timings due to interrupt latencies. The programmable
acquisition and control timer (PACT) acts as a coprocessor combining configurable capture and compare
features, within a flexible dual-port RAM, able to run real-time tasks with little or no CPU intervention. The PACT
structure allows concatenation of tasks, thus enabling the CPU to perform data manipulation while the PACT
module both captures and outputs real-time-related information. Since all the PACT control information is held
within the dual-port Ram, the CPU can access these parameters quickly.
To use the PACT, the user must set up three distinct areas of memory. The first is the dual-port RAM, which
contains the capture area, the commands, and the timer definitions. The second is the peripheral frame. The
third is an area near the end of the program memory which holds the interrupt vectors of PACT.
