The triple-timer counter (TTC) can generate periodic interrupts or can be used to count the widths of signal pulses from an MIO pin or from the PL.

There are four TTCs in the LPD. Each TTC has its own set of control and status registers that are accessed via its 32-bit APB programming interface attached to the LPD IOP switch. Each TTC can be individually protected by the LPD_XPPU protection unit. All three timer/counters within a TTC must have the same security status because a single APB programming interface serves the entire TTC.
