System bus frequency
CLKOUT period
Control input valid to CLKOUT high
BKPT valid to CLKOUT high
CLKOUT high to control inputs invalid
CLKOUT high to asynchronous control input BKPT invalid
Data input (D[31:0]) valid to CLKOUT high
CLKOUT high to data input (D[31:0]) invalid
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 CLKOUT output.
All other timing relationships can be derived from these values.
