4.9.3
There are three PLLs inside the i.MX35, all based on the same PLL design. The reference clock for these
PLLs is normally generated from an external 24-MHz crystal connected to an internal oscillator via
EXTAL24M and XTAL24 pins. It is also possible to connect an external 24-MHz clock directly to
EXTAL24M, bypassing the internal oscillator.

ETM is an ARM protocol. The timing specifications in this section are given as a guide for a test point
access (TPA) that supports TRACECLK frequencies up to 133 MHz.
