MPC5554 Microcontroller Product Brief, Rev. 2.1

Freescale Semiconductor

9

— A TAP controller state machine that controls the operation of the data registers, instruction

register and associated circuitry

•

Voltage regulator controller

— Provides a low cost solution to power the core logic. It reduces the number of power supplies

required from the customer power supply chip.

•

POR block

— Provides initial reset condition up to the voltage at which pins (RESET) can be read safely. It

does not guarantee the safe operation of the chip at specified minimum operating voltages.
