Notes
2. TCPWM: Timer, Counter, and Pulse Width Modulator. 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. When using the capacitive sensing functionality, Pad 2 (P4.0) must be connected to a C
MOD
capacitor (located off of Cypress BLE Module). The value of this
capacitor is 2.2 nF and should be placed as close to the module as possible.
5. The main board needs to connect all GND connections (Pad 25/26/27/28) on the module to the common ground of the system.
6. 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
