10.3.13.2. Implementation Details

Each Cortex®-A9 processor has a private 64‑bit comparator that generates a private interrupt when the counter reaches the specified value. Each Cortex‑A9 processor uses the banked ID, ID27, for this interrupt. ID27 is sent to the GIC as a Private Peripheral Interrupt (PPI).

The global timer is clocked by mpu_periph_clk, running at ¼ the rate of mpu_clk.
