: tpu_tsm_int_lev
: To program the level of interrupt from the TPU-TSM function.
: This function has 2 parameters:
: tpu_tsm_int_chk
: Interrupt check for TSM interrupt service request match.
: This function has 3 parameters:
*tpu - This is a pointer to the TPU3 module to use. It is of
level - The interrupt level (0 to 31).
*tpu - This is a pointer to the TPU3 module to use. It is of
type TPU3_tag which is defined in m_tpu3.h
