Frequency of operation
E-clock period
Peripheral data setup time
Peripheral data hold time
Delay time, peripheral data write
Port C input data setup time
Port C input data hold time
Delay time, E fall to STRB
Setup time, STRA asserted to E fall
Delay time, STRA asserted to port C data output valid
Hold time, STRA negated to port C data
3-state hold time
1. V
2. Ports C and D timing is valid for active drive. (CWOM and DWOM bits are not set in PIOC and SPCR registers,
3. If this setup time is met, STRB acknowledges in the next cycle. If it is not met, the response may be delayed one more cycle.
