#   ROUTINE: COMBINE 16-BIT VALUE (0x23A54)
#       Parameters:
#           r4 = (lowValue) 6-bit value to be stored in low 6 bits
#           r5 = (highValue) 10-bit value to be stored in high 10 bits
#       Returns:
#           r2 = Combined 16-bit value
#               (Bits 0 to 5) lowValue
#               (Bits 6 to 15) highValue
