First, the value read from the counter now ranges from 48,000 to 74,600.
Because the counter is only 16 bits wide (maximum value 65,535), higher tem-
peratures will cause the counter to overflow. The software will need to detect this
condition, probably by programming the timer to generate an interrupt on roll-
over and setting a flag when this interrupt occurs. This approach does, however,
add to the overall interrupt processing latency of the system.
The second effect of changing the period of the MAX6576 output is the time
required to get a result. At the new setting, temperature readings can be made
only once every 9.6 ms (at 30
C) to 14.9 ms
