General Purpose I/O Module
12.3.1.8.6 Timer Drive Strength Control Register (DSCR_TIMER)
The DSCR_TIMER register controls the output drive strengths of the following pins: DT3IN,
DT3OUT, DT2IN, DT2OUT, DT1IN, DT1OUT, DT0IN, and DT0OUT.

12.4.1 Overview
Initial pin function is determined during reset configuration. The pin assignment registers allow
the user to select among various primary functions and general purpose I/O after reset.
Most pins are configured as general purpose I/O by default. The notable exceptions to this are
external bus control pins, address/data pins, and chip select pins. These pins are configured for
their primary functions after reset.
Every general purpose I/O pin is individually configurable as an input or an output via a data
direction register (PDDR_x).
Every GPIO port has an output data register (PODR_x) and a pin data register (PPDSDR_x) to
monitor and control the state of its pins. Data written to a PODR_x register is stored and then
driven to the corresponding port x pins configured as outputs.
Reading a PODR_x register returns the current state of the register regardless of the state of the
corresponding pins.
