Note
: The frequency of the clock input CKi is assumed to be at the output bit rate. However, it can be at twice the bit rate in the Internal
Timing Mode.
AC Electrical Characteristics
- Serial Port, RESET, WD Timer and IRQ Release Time
(Figures 19, 20, 21 and 22).
Voltages are with respect to ground (V
