The parameters in this chapter partly represent the characteristics of the C161U and
partly its demands on the system. To aid in interpreting the table correctly when
evaluating parameters for a design, the following notation is used in the column
“Symbol”:
CC (Controller Characteristics):
The logic of the C161U will provide signals with the respective timing characteristics.
SR (System Requirement):
The external system must provide signals with the respective timing characteristics to
the C161U.
24.7.1
The internal operation of the C161U is controlled by the internal CPU clock f
edges of the CPU clock can trigger internal (eg. pipeline) or external (eg. bus cycles)
operations. The specification of the external timing (AC Characteristics) therefore
depends on the time between two consecutive edges of the CPU clock, called “TCL”
(see Figure 126).
For timing purposes a port pin is no longer floating when a 100 mV change from load
voltage occurs, but begins to float when a 100 mV change from the loaded
