AC Electrical Characteristics
The AC characteristics consist of output delays, input setup and hold times, and signal skew times. All
signals are specified relative to an appropriate edge of other signals. All timing specifications are specified
at a system operating frequency (HCLK) from 0 MHz to 133 MHz (core operating frequency 266 MHz)
with an operating supply voltage from V
