short question concerning usb jump table

Hello,

I am writing a firmware with keil uvision2 which has to use the UART.
Unfortunately, I'm writing the jump table

XXXXX code (ISR_com) 
extrn code (ISR_Sudav, ... , ISR_Ep0in, ... )

; Interrupt Vectors

CSEG AT 23H 
SERIAL_AutoVector equ $ + 2
ljmp SERIAL_Jump_Table 

CSEG AT 43H
USB_AutoVector equ $ + 2
ljmp USB_Jump_Table

where ISR_com is my serial port interrupt.
But I'm unable to find what should be written instead of XXX ! If I'm right, it should be stg like SERIAL PORT !?

Thank you in advance,

stephane

I apologize! I was sure I had written that. I'm using the EZ-USB FX developer's kit CY3671 with the CY7C64613-128NC chip.

Thank you for your help,

Stephane.

The serial interrupt does not use an autovector scheme. It is just a plain 8052 interrupt. Use the following in a C file.
void serialIsr( void ) interrupt 4 using?? { }

For a C implementation of the autovector scheme, be sure to check the following application note:
