8 / 33 page 8 TABLE 8. MISCELLANEOUS CONTROL PORT PINS PIN NAME PIN NUMBER PIN I/O TYPE DESCRIPTION GRESET L15 I Global Reset for MAC, Active LOW TCLKIN(CS) L4 I/O, 50K Pull Down CS used for Chip Select Output for Serial Devices which have a 4 wire interface like the AST45DB011 and also serial data on two wire devices like the 24C08. ANTSEL N15 O The antenna select signal changes state as the receiver switches from antenna to antenna during the acquisition process in the antenna diversity mode. This is a complement for ANTSEL (pin 40) for differential drive of antenna switches. ANTSEL N16 O The antenna select signal changes state as the receiver switches from antenna to antenna during the acquisition process in the antenna diversity mode. This is a complement for ANTSEL (pin 39) for differential drive of antenna switches. Test_Mode C4 I Must be tied to GND. CompCap1 R15 I Compensation Capacitor. CompCap2 R13 I Compensation Capacitor. CompRes1 T15 I Compensation Resistor. CompRes2 P13 I Compensation Resistor. DBG4 (MPCIACT) B6 I/O Manufacturing Debug Signals, Leave Unconnected. Connected to MPCIACT Signal on Mini-PCI Connector. DBG3 (CLKRUN) A5 I/O Manufacturing Debug Signals, Leave Unconnected. Connected to CLKRUN Signal on Mini-PCI Connector. DBG2 (LED2) C5 I/O Manufacturing Debug Signals, Leave Unconnected. Used as LED2 Output Signal. DBG1 B5 I/O Manufacturing Debug Signals, Leave Unconnected. DBG0 A6 I/O Manufacturing Debug Signals, Leave Unconnected. TABLE 9.
