DSP56001 Electrical Characteristics
AC Electrical Characteristics - SCI Timing
(Vcc = 5.0 Vdc + 10%, TJ = -40 to +105° C, CL = 50 pf + 1 TTL Load at 20.5 MHz and 27 MHz,
Vcc = 5.0 Vdc + 5%, TJ = -40 to +105° C, CL = 50 pf + 1 TTL Load at 33 MHz,
see SCI Figures 1 and 2)
cyc = Clock cycle = 1/2 instruction cycle = 2 T cycles
tACC = Asynchronous clock cycle time
tACC = Asynchronous Clock Cycle Time (for internal clock tACC is determined by the SCI clock control register and Icyc)
SCI Asynchronous Mode Timing - 1X Clock
