4. PHYSICAL INTERFACE
4.1
Power
Supply
The transient response of the regulator is important. If the power rails of the module are
supplied from an external voltage source, the transient response of any regulator.
4.2
General
Purpose
IO
There are nine general purpose digital IOs defined in the module. It can configure whether
peripheral modules control certain pins or whether they are under software control, and if so,
whether each pin is configured
as an input or output and if a pullup or pulldown resistor in the pad is connected. Each
peripheral that connectsto the I/O pins can choose between two different I/O pin locations to
ensure flexibility in various applications.
4.3 UART
This is a standard UART interface for communicating with other serial devices. The UART
interface provides a simple mechanism for communicating with other serial devices using the
RS232 protocol.
When the module is connected to another digital device,UART_RX and UART_TX transfer
data between the two devices.
4.4 I2C
Any three PIOs can be used as a master I2C interface by configuring the hardware bit serialiser
with suitable firmware. The strong pull-ups in the PIO pads eliminate the need for external pull-
up resistors.
4.5 Debugger Support
The two pin Serial Wire Debug (SWD) interface provided as a part of the Debug Access Port
(DAP) offers a flexible and powerful mechanism for non-intrusive debugging of program code.
Breakpoints and single stepping are part of this support.

undesired operation.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to
operate the equipment.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
This equipment generates uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be

following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
-Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
-Consult the dealer or an experienced radio/TV technician for help
Important announcement
LABEL OF THE END PRODUCT:
The final end product must be labeled in a visible area with the following" Contains TX FCC ID: 2AB2RJS-BLMN5F31

Operation is subject to the following two conditions: (1) this device may not cause harmful interference and (2) this device must
accept any interference received, including interference that may cause undesired operation.
To comply with FCC regulations limiting both maximum RF output power and human exposure to RF radiation, the maximum
antenna gain including cable loss in a portable exposure condition must not exceed -1dBi.
A user manual with the end product must clearly indicate the operating requirements and conditions that must be observed to
ensure compliance with current FCC RF exposure guidelines.
The end product with an embedded Module may also need to pass the FCC Part 15 unintentional emission testing requirements
and be properly authorized per FCC Part 15.
