Notes
2. TCPWM stands for timer, counter, and PWM. If supported, the pad can be configured to any of these peripheral functions.
3. TCPWM connections on ports 0, 1, 2, and 3 can be routed through the Digital Signal Interconnect (DSI) to any of the TCPWM blocks and can be either positive
or negative polarity. TCPWM connections on ports 4 and 5 are direct and can only be used with the specified TCPWM block and polarity specified above.
4. The main board needs to connect both GND connections (Pad 1 and Pad 10) on the module to the common ground of the system.
5. When using the capacitive sensing functionality, Pad 2 (P4.1) can be connected to a C
TANK
capacitor (located off of Cypress Bluetooth LE Module). C
Tank
should
be used if implementing a shield layer on the capacitive sensor. If used, this capacitor should be placed as close to the module as possible.
6. When using the capacitive sensing functionality, Pad 21 (P4.0) must be connected to a C
MOD
capacitor (located off of Cypress Bluetooth LE Module). The value
of this capacitor is 2.2 nF and should be placed as close to the module as possible.
7. If the I
2
S feature is used in the design, the I
2
S pins shall be dynamically routed to the appropriate available GPIO by PSoC Creator
