16 MHz is the maximum input frequency when using an external crystal oscillator; however, 40 MHz
can be applied with an external clock source.
If wait states are used, add 2t
Assuming back-to-back bus cycles.
When forcing wait states using the BUSCON register, add 2t
Exceeding the maximum specification causes additional wait states.
8-bit bus only.
The first falling edge of READY is not synchronized to a CLKOUT edge; therefore, one programmed
wait state is required.
Device is static by design but has been tested only down to 20 MHz.
Assumes CLKOUT is operating in divide-by-two mode (f/2).
CLKOUT High to WR# Rising Edge
WR# Low to WR# High
Data Hold after WR# Rising Edge
BHE#, INST Hold after WR# High
A20:0, CS x # Hold after WR# High
BHE#, INST Hold after RD# High
A20:0, CS x # Hold after RD# High
A20:0 Valid to READY Setup
READY Hold after CLKOUT Low
Non READY Time
