nsdsp_debug_read_cp0

This function is specific to PIC32M and reads the content of a CP0 register.

Syntax

unsigned int nsdsp_debug_read_cp0(
        nsdsp_session_t   session,
        unsigned int      reg,
        unsigned int      sel
);

Parameters

session - a reference to the Debug Session Object obtained with nsdsp_session_program_for_debug or nsdsp_start_debug_session function

reg - the number of the CP0 register

sel - the selector of the CP0 register

Return

The function returns four if successful, or zero in case of error.

Notes

This instruction only queues a command. The command will be sent to NSDSP when you queue enough commands to fill the buffer or when you call nsdsp_session_flush.

Once the data arrives, you can retrieve the value of the register with nsdsp_debug_fetch_word function.
