commands would be:
; set ConfigCtrl1 all bits Low
; set ConfigCtrl2 bits 7 and 6 Low
; set ConfigCtrl2 bit 4 High
; set ConfigCtrl2 bit 3 High
; read SramData LSB Register
; SramData LSB Register data
; write SramData LSB Register
; write SramData MSB Register
; read SramData LSB Register
; SramData LSB Register data
; read SramData MSB Register
; SramData MSB Register data
; set ConfigCtrl2 bit 3 Low
