3 PCL SIGNAL SUMMARY

Figure 1 shows the connections to the PCL.

Pin name prefixes:

• I - input
• O - output
• B - bi-directional

Types:

• 8 - 8mA output driver.
• 4 - 4mA output driver.
• 4R - 4mA output driver with limited slew rate.
• 2 - 2mA output driver.
• U - input with pullup resistor.
• D - bidirectional pin with pulldown resistor.
• S - Schmitt trigger input. May be driven by an integrator/delay.

Naming convention: Input signal names begin with `I', output signal names begin with `O' and bi-directional signal names begin with `B'. For historical reasons names are restricted to four characters or less.

See Section 6.4 for rise and fall times of output signals.
