Programmable Interrupt Timers (PIT0–PIT3)
19.1
This chapter describes the operation of the four programmable interrupt timer modules: PIT0–PIT3.
19.1.1
Each PIT is a 16-bit timer that provides precise interrupts at regular intervals with minimal processor
intervention. The timer can count down from the value written in the modulus register or it can be a
free-running down-counter.
19.1.2
19.1.3
This subsection describes the operation of the PIT modules in low-power modes and debug mode of
operation. Low-power modes are described in the power management module,
Management.” Table 19-1
