VFD Controller
Bit 7 (IDLE) : SLEEP or IDLE mode control as set by SLEP instruction.
0/1 ꢂSLEEP 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.

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.
