For data input, only the lower 8 bits (D0 to D7) are valid. 17 to 24 D0 to D7 Output Data bus (in 16-bit mode) These pins are held in the output off state when BUSWD is low. 25 to 32 D8 to D15 I/O Connections for the system clock crystal oscillator circuit. The XIN pin can also be used as an external clock signal input. 64 1 XIN XOUT Input Baseband (multiplex) signal input 53 MPXIN – + Output Subcarrier output (76 kHz bandpass filter output) 55 FLOUT Continued on next page. |
