    Question: What are the Special Function Registers (SFRs) associated with the serial ports of an FX2LP device?



    These are the SFRs for FX2LP serial ports. For more information, see the corresponding register tables in the EZ-USB Technical Reference Manual:

    PCON (SFR 0x87) Bit 7, Serial Port 0 rate control SMOD0 (Table 14-13)

    SCON0 (SFR 0x98) Serial Port 0 control (Table 14-11)

    SBUF0 (SFR 0x99) Serial Port 0 transmit/receive buffer

    EICON (SFR 0xD8) Bit 7, Serial Port 1 rate control SMOD1 (Table 14-12)

    SCON1 (SFR 0xC0) Serial Port 1 control (Table 14-14)

    SBUF1 (SFR 0xC1) Serial Port 1 transmit/receive buffer

    T2CON (SFR 0xC8) Baud clock source for modes 1 and 3 (Table 14-5)

    UART230 (0xE608) High-Speed Baud Rate Generator enable (Section 14.3.2)

    Note: The registers PCON and EICON include functionalities that are not part of the serial interface.
