R5F64188DFB芯片概述:
  Wait Mode
  In wait mode, the CPU clock is turned off, so are the CPU (because operated by the CPU clock) and the watchdog timer. However, if the PM22 bit of PM2 register is “1” (On-chip Oscillator clock for the watchdog timer count source), the watchdog timer remains active. Because the main clock, and On-chip Oscillator clock are on, the peripheral functions using these clocks keep operating.
  -Peripheral Function Clock Stop Function
  If the CM02 bit is “1” (peripheral function clocks turned off during wait mode), the f1, f2, f8, f32, f1SIO,f8SIO, and f32SIO clocks are turned off when in wait mode, with the power consumption reduced that Much.
  - Entering Wait Mode
  The microcomputer is placed into wait mode by executing the WAIT instruction.
  - Pin Status During Wait Mode
  Table 1.7.3 lists pin status during wait mode
  - Exiting Wait Mode
  The microcomputer is moved out of wait mode by a hardware reset or peripheral function interrupt.If the microcomputer is to be moved out of exit wait mode by a hardware reset, set the peripheral function interrupt priority ILVL2 to ILVL0 bits to “0002” (interrupts disabled) before executing the WAIT instruction
