disabled (PTxSE[n] = 0), low drive strength selected (PTxDS[n] = 0), and internal pullups disabled
(PTxPE[n] = 0). Two exceptions to this are the RESETB and BKGD/MS pins, which have pullups enabled
at reset.
4.1.5.2
The RESETB is an open drain device, and cannot be programmed to an active high.
4.1.5.3
PTB3 and PTB1 pins have twice the output drive capability of other digital pins, and can source 15 to
20 mA. This allows you to interface SCI1 and SCI2 TX pins (which can mapped to these ports) directly
to opto-isolators.
4.1.5.4
PTE4, PTE5 and PTE6 are open drain devices. These pins do not include active pullup capability (although
they do have input pullups when used as input functions). The intention here is to allow the device to
interface (via off-chip pullup resistors) to 5 V logic. PTE4 can be programmed to MISO3 or MOSI3. PTE5
can be programmed to SCLK3. PTE6 can be programmed as SS3 or TX2.

High Drive Outputs
Open Drain Outputs
Not all general-purpose I/O pins are available on all packages. To avoid
extra current drain from floating input pins, the user’s reset initialization
routine in the application program must either enable on-chip pullup devices
or change the direction of unconnected pins to outputs so the pins do not
float.
