General Purpose I/O Module
Initial pin output drive strength is determined during reset configuration. The DSCR_x registers
allow the pin drive strengths to be configured on a per-function basis after reset.
The MCF5271 ports module does not generate interrupt requests.
12.4.2 Port Digital I/O Timing
Input data on all pins configured as general purpose input is synchronized to the rising edge of the
internal bus clock, CLKOUT, as shown in
Data written to the PODR_x register of any pin configured as a general purpose output is
immediately driven to its respective pin, as shown in
12.5
The initialization for the MCF5271 ports module is done during reset configuration. All registers
are reset to a predetermined state. Refer to
more details on reset and initialization.
