115 / 407 page  CP3SP33 www.ti.com SNOSCW5 – MAY 2013 18.2.7 Port Weak Pullup/Pulldown Enable Register (PxWPU) The PxWPU register controls whether a weak pullup or pulldown device is enabled on the output buffer. The pullup or pulldown device, if enabled by the register bit, operates whenever the port output buffer is disabled (TRI-STATE mode). Enabling the pullup or pulldown device is unaffected by whether the port pin is in GPIO or alternate function mode. A reset operation clears the PxWPU registers, which disables all pullups and pulldowns. 15 0M PxWPU PxWPU The Weak Pullup/Pulldown Enable bits control whether the weak pullup/pulldown device is enabled. 0 – Weak pullup/pulldown disabled. 1 – Weak pullup/pulldown enabled. 18.2.8 Port Weak Pullup/Pulldown Direction Register (PxPDR) The PxPDR register selects whether a weak pullup or pulldown device is enabled on the output buffer. The pullup or pulldown device, if enabled in the PxWPU register, operates whenever the port output buffer is disabled (TRI-STATE mode). The PxPDR bits are ignored unless the corresponding PxWPU bits are set. At reset, the registers are initialized to FFFFh, which selects pullups. 15 0M PxPDR PxPDR The Pullup/Pulldown Direction bits select between a pullup and a pulldown device. 0 – Pulldown selected. 1 – Pullup selected. 19 Bluetooth Controller The integrated hardware Bluetooth Lower Link Controller (LLC) complies to the Bluetooth Specification Version 1.2 and integrates the following functions: • 7K-byte dedicated Bluetooth data RAM • 1K-byte dedicated Bluetooth sequencer RAM • Support of all Bluetooth 1.2 packet types • Support for fast frequency hopping of 1600 hops/s • Access code correlation and slot timing recovery circuit • Power Management Control Logic • BlueRF-compatible interface to connect with National’s LMX5252 and other RF transceiver chips For a detailed description of the interface to the LMX5252, consult the LMX5252 data sheet which is available from the Texas Instruments wireless group. National provides software libraries for using the Bluetooth LLC. Documentation for the software libraries is also available from National Semiconductor. 19.1 RF Interface The CP3SP33 interfaces to the LMX5251 or LMX5252 radio chips though the RF interface. Figure 19-1 shows the interface between the CP3SP33 and the LMX5251 radio chip.
