Parallel I/O Signals
Table 25. PIO Outputs
The inputs can be used synchronously or asynchronously (in relation to MCKI).
For synchronous PIO inputs, certain setup/hold constraints must be met. These constraints are shown in the Table 26 and
are represented in Figure 10.
For asynchronous inputs, a minimum pulse width is necessary as shown in Table 27 and as represented in Figure 10.
