2.1 I/O Ports

Each I/O port can be configured as an input or output. When configured as input, each I/O port, except pins

P1_0 and P1_1, can also be configured with internal pull-up, pull-down or tri-state. Pull-down or pull-up can

only be configured to whole port, not individual pins. Unused I/O pins should have defined level and not be

floating. See the Profile Toolkit developer guide for more information about the configuration.

During reset the I/O pins are configured as inputs with pull-ups. P1_0 and P1_1 are inputs but do not have

pull-up or pull-down.

2.2 UART

UART baud rate can be configured up 2 Mbps. See the Profile Toolkit developer guide for more information.
