Question: 

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

Answer: 

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.
