# PARAMETERS:	devID  - This parameter is used to specify the device 
#                        under configuration
#
#		enable	- 0 (disable), 1 (enable)
#
# NOTES: The ESSI block must be enable in the following sequence 
#	 1) Enable the ESSI block 
#	 2) De-assert the ESSI block reset
#
#	 The ESSI block must be disabled in the following sequence
#	 1) Assert the ESSI block reset
#	 2) Disable the ESSI block
