The data returned between bytes 55 and 237 of the

previous table is interpreted using Position_last and the

following table. The key to identifying the data located in

byte 55 is to locate the DATA corresponding to POSITION

= Position_last in the next table. Subsequent bytes are

identified by decrementing the value of POSITION. For

example: If Position_last = 9 then the first data returned

in byte position 55 of a block read is Status_temperature

of page 0 followed by Read_temperature_1[15:8] of page

0 followed by Read_temperature_1[7:0] of page 0 and so

on. See Table 5.
