VFD Controller
Bit 7 (IDLE) : SLEEP or IDLE mode control as set by SLEP instruction.
0/1 SLEEP mode/IDLE mode.
This bit allows SLEP instruction to decide which power saving mode to
execute. The status after wake-up and the wake-up source list is as the shown
below.

PORTC(0~3)(Key1~Key4)
Reset and Jump 1) Wake-up
RE PAGE0 Bit3 or Bit4 or Bit5 or Bit6 = 1 to Address 0 2) Jump to next instruction after SLEP
PORT9(1~4)
IOCF Bit4 or Bit5 or Bit6 =1 or Bit7=1
Reset and Jump 1) Wake-up
to Address 0 2) Jump to next instruction after SLEP
NOTES: 1 PORT90 wakeup function is controlled by IOCF Bit 3. It is a falling edge or rising edge
trigger (controlled by CONT register Bit7).
2. PORT91 wakeup function is controlled by IOCF Bit 4. It is a falling edge trigger.
3. PORT92 ~ PORT94 wakeup functions are controlled by IOCF. They are falling edge
triggers.
4. PORTC0 ~ PORTC3 wakeup functions are controlled by RE PAGE0 Bit 0 ~ Bit 3. They are
falling edge triggers.
This specification is subject to change without further notice.
