In application code, the user reads the temperature sensor channel, calculates V
TEMP
, and
compares to V
TEMP25
. If V
TEMP
is greater than V
TEMP25
the cold slope value is applied in
the preceding equation. If V
TEMP
is less than V
TEMP25
, the hot slope value is applied in
the preceding equation. ADC Electricals table may only specify one temperature sensor
slope value. In that case, the user could use the same slope for the calculation across the
operational temperature range.
For more information on using the temperature sensor, see the application note titled
Temperature Sensor for the HCS08 Microcontroller Family
(document AN3031).
11.4.9 MCU wait mode operation
Wait mode is a lower-power consumption Standby mode from which recovery is fast
because the clock sources remain active.
If a conversion is in progress when the MCU enters Wait mode, it continues until
completion. Conversions can be initiated while the MCU is in Wait mode by means of
the hardware trigger or if continuous conversions are enabled.
The bus clock, bus clock divided by two; and ADACK are available as conversion clock
sources while in Wait mode. The use of ALTCLK as the conversion clock source in Wait
is dependent on the definition of ALTCLK for this MCU. See the Chip Configuration
information on ALTCLK specific to this MCU.
If the compare and hardware averaging functions are disabled, a conversion complete
event sets SC1n[COCO] and generates an ADC interrupt to wake the MCU from Wait
mode if the respective ADC interrupt is enabled, that is, when SC1n[AIEN]=1. If the
hardware averaging function is enabled, SC1n[COCO] will set, and generate an interrupt
if enabled, when the selected number of conversions are completed. If the compare
function is enabled, SC1n[COCO] will set, and generate an interrupt if enabled, only if
the compare conditions are met. If a single conversion is selected and the compare trigger
is not met, the ADC will return to its idle state and cannot wake the MCU from Wait
mode unless a new conversion is initiated by the hardware trigger.
11.4.10 MCU Normal Stop mode operation
Stop mode is a low-power consumption Standby mode during which most or all clock
sources on the MCU are disabled.
