Power Control
The cursor control instruction (Figure 12) includes the AMP, SLP, and STB bits.
AMP:
When AMP = 1, each voltage-follower for V1 to V5 pins and the booster are turned on. When
AMP = 0, current consumption can be reduced while character or segment display controlled by the
multiplexing drive method is not being used.
SLP:
When SLP = 1, the
HD66705U
enters sleep mode, where all the internal operations are halted except
for annunciator display function and the R-C oscillator, thus reducing current consumption. Refer to the
Sleep Mode section. Only the following instructions can be executed during sleep mode.
a. Annunciator address set (AAN)
b. Annunciator data write
c. Annunciator display on or off (DA = 1 or 0)
d. Voltage-follower on or off (AMP = 1 or 0)
e. Standby mode set (STB = 1)
f.
Sleep mode cancel (SLP = 0)
During sleep mode, other RAM data and instructions cannot be updated but they are retained.
STB:
When STB = 1, the
HD66705U
enters standby mode, where the device completely stops, halting all the
internal operations including the internal R-C oscillator and no external clock pulses are supplied.
However, annunciator display alone is available when the alternating signal for annunciator-driving signals
is supplied to the EXM pin. When the annunciator display is not needed, make sure to turn off display (DA
= 0). Refer to the Standby Mode section. Only the following instructions can be executed during standby
mode.
a. Annunciator address set (AAN)
b. Annunciator data write
c. Annunciator display on or off (DA = 1 or 0)
d. Voltage-follower on or off (AMP = 1 or 0)
e. Start oscillator
f.
Standby mode cancel (STB = 0)
During standby mode, RAM data and other instructions may be lost; they must be set again after standby
mode is cancelled.
