Signals above are shown in relation to the clock. No relationship between
signals is implied or intended.
All processor bus timings are synchronous; that is, input setup/hold and
output delay with respect to the rising edge of a reference clock. The
reference clock is the SCLK output. All other timing relationships can be
derived from these values.
