JTAG and Boundary Scan Timing
1 Output numbers depend on the value programmed into the IFDR; an IFDR programmed with the
maximum frequency (IFDR = 0x20) results in minimum output timings as shown in Table 21. The
I2C interface is designed to scale the actual data transition time to move it to the middle of the
SCL low period. The actual position is affected by the prescale and division values programmed
into the IFDR; however, the numbers given in Table 21 are minimum values.
2 Because SCL and SDA are open-collector-type outputs, which the processor can only actively
drive low, the time SCL or SDA take to reach a high level depends on external signal capacitance
and pull-up resistor values.
3 Specified at a nominal 50-pF load.
