Port Operation Timing
Writing to a Port (Output)
When an operation induces a modification of the
content in a port register, the new value is placed at the
output of the D flip-flop during the T12 period of the last
machine cycle that the instruction needed to execute.
It is important to note, however, that the output stage
only samples the output of the registers on the P1
phase of each period. It follows that the new value only
appears at the output after the T12 period of the
following machine cycle.
Reading a Port (Input)
The reading of an I/O pin takes place:
During T9 cycle for P0, P1
During T10 cycle for P2, P3
When the ports are configured as I/Os (see
Figure 25).
In order to get sampled, the signal duration present on
the I/O inputs must have a duration longer than
Fosc/12.
I/O Ports Driving Capability
The maximum allowable continuous current that the
device can sink on I/O port is defined by the following:
Maximum sink current on one given I/O
Maximum total sink current for P0
Maximum total sink current for P1, 2, 3
Maximum total sink current on all I/O
It is not recommended to exceed the sink current
expressed in the above table. Doing so is likely to
make the low-level output voltage exceed the device’s
specification and it is likely to affect the device’s
reliability.
The VRS550 / VRS560 port are not designed to source
current.
