10 66AK2H14/12/06 Peripheral Information and Electrical Specifications
This chapter covers the various peripherals on the 66AK2H14/12/06 device. Peripheral-specific information, timing
diagrams, electrical specifications, and register memory maps are described in this chapter.
10.1 Recommended Clock and Control Signal Transition Behavior
All clocks and control signals must transition between V_IH and V_IL (or between V_IL and V_IH) in a monotonic
manner.
10.2 Power Supplies
The following sections describe the proper power-supply sequencing and timing needed to properly power on the
66AK2H14/12/06. The various power supply rails and their primary functions are listed in Table 10-1.
