Power-Down Control

This chapter describes the controls used to reduce power consumption of the device.

Points on power saving

The current consumption of the device varies greatly with the CPU's operation mode, the system clocks used,
and the peripheral circuits operated.

To reduce power consumption of the device, it is important that as many unnecessary circuits as possible be
turned off. In particular, peripheral circuits operating at a fast-clock rate consume a large amount of current,
so design the program so that these circuits are turned off whenever unnecessary.

Power-saving in standby modes

When CPU processing is unnecessary, such as when waiting for an interrupt from key entries or peripheral
circuits, place the device in standby mode to reduce current consumption.

Standby mode

Method to enter the mode

Circuits/functions stopped

Basic HALT mode

Execute the halt instruction after setting HLT2OP
(D3)/Clock option register (0x40190) to "0".
When the #BUSREQ signal is asserted from an
external bus master while SEPD (D1)/Bus control
register (0x4812E) = "1".

CPU (DMA cannot be used.)

HALT2 mode

Execute the halt instruction after setting HLT2OP
to "1".

CPU, BCU, bus clock, and DMA

SLEEP mode

Execute the slp instruction.

CPU, BCU, bus clock, DMA, high-speed
(OSC3) oscillation circuit, prescaler, and
peripheral circuits that use the prescaler
output clocks

HLT2OP (D3)/Clock option register (0x40190) that is used to select a HALT mode is set to "0" (basic HALT
mode) at initial reset.

Notes: • In systems in which DRAM or SDRAM is connected directly to the device, the refresh function is

turned off during HALT2 and SLEEP modes. However, the SDRAM self refresh function can be
used by activating it before the CPU enters HALT2 or SLEEP mode.

• The  standby mode is cleared by interrupt generation (except for the basic HALT mode, which is

set using an external bus master). Therefore, before entering standby mode, set the related
registers to allow an interrupt to be used to clear the standby mode to be generated.

• When clearing the standby mode with an interrupt from port input, the interrupt operates as a

level interrupt regardless of the interrupt trigger setting. When edge trigger is set for the interrupt
trigger, attention must be paid to the port level during standby mode.

The low-speed (OSC1) oscillation circuit and clock timer continue operating even during SLEEP mode. If
they are unnecessary, these circuits can also be turned off.

Switching over the system clocks

Normally, the system is clocked by the high-speed (OSC3) oscillation clock. If high-speed operation is
unnecessary, switch the system clock to the low-speed (OSC1) oscillation clock and turn off the high-speed
(OSC3) oscillation circuit. This helps to reduce current consumption. However, if DRAM is connected
directly to the device, note that the refresh function is also turned off.
Even during operation using the high-speed (OSC3) oscillation clock, power reduction can also be achieved
through the use of a system clock derived from the OSC3 clock by dividing it (1/1, 1/2, 1/4, or 1/8).
