    Using a single instruction to process simultaneously can cause a malfunction of the CPU. (4) The S1C63632 supports the SLEEP function and both the OSC1 and OSC3 oscillation circuits stop oscillat- ing when the CPU enters SLEEP mode. To prevent the CPU from a malfunction when it resumes operating from SLEEP mode, switch the CPU clock to OSC1 before placing the CPU into SLEEP mode.

  • Page 180: Summary Of Notes

    UMMARY OF OTES 5.1 Notes for Low Current Consumption The S1C63632 contains control registers for each of the circuits so that current consumption can be reduced. These control registers reduce the current consumption through programs that operate the circuits at the minimum levels.

    0000H to 00FFH. Therefore, pay attention to the SP1 value because it may be set to 0200H or more exceeding the 4-bit/16-bit accessible range in the S1C63632 or it may be set to 00FFH or less. Memory accesses except for stack operations by SP1 are 4-bit data access. After initial reset, all the interrupts including NMI are masked until both the stack pointers SP1 and SP2 are set by software.
  • Page 182 CHAPTER 5: SUMMARY OF NOTES (4) The S1C63632 supports the SLEEP function and both the OSC1 and OSC3 oscillation circuits stop oscillat- ing when the CPU enters SLEEP mode. To prevent the CPU from a malfunction when it resumes operating from SLEEP mode, switch the CPU clock to OSC1 before placing the CPU into SLEEP mode.
