Figure3.25.2 Example External Circuitry for Using the PMC
Figure3.25.2 shows an example of external circuitry for using the PMC.
In normal mode, the power management pin (PWE) outputs "1" and power is supplied to all
the blocks in the TMP92CZ26A.
In the Power Cut Mode, the power management pin (PWE) outputs "0" and power is cut off for
the internal circuitry excluding the CPU, part of internal RAM, AD converter and RTC to
reduce leak current. In the Power Cut Mode, power is supplied to only the I/O (including the AD
pins), TSI circuit, 16 Kbytes of internal RAM, low-frequency oscillation circuit, RTC and PMC.
