tions are unavailable. When each peripheral function is used for the first time, be sure to set the corresponding bit of
the low power consumption registers (POFFCRn) to "1" in the initial settings of the program (before operating the
control register for the peripheral function).
(POFFCRn) must not be changed to "0". If it is changed, the peripheral function may operate unexpectedly.
The TMP89FM42 has low power consumption registers (POFFCRn) that save power when specific peripheral
The basic clock supply to each peripheral function is disabled for power saving, by setting the corresponding bit of
After reset, the low power consumption registers (POFFCRn) are initialized to "0", and thus the peripheral func-
