STANDBY FUNCTIONS
The
μ
PD17246 is provided with HALT and STOP modes as standby functions.
By using the standby function, current consumption can be reduced.
In the HALT mode, the program is not executed, but the system clock f
X
is not stopped. This mode is maintained,
until the HALT mode release condition is satisfied.
In the STOP mode, the system clock is stopped and program execution is stopped. This mode is maintained, until
the STOP mode release condition is satisfied.
The HALT mode is set, when the HALT instruction has been executed. The STOP mode is set, when the STOP
instruction has been executed.
9.1
HALT Mode
In this mode, program execution is temporarily stopped, with the main clock continuing oscillation, to reduce current
consumption.
Use the HALT instruction to set the HALT mode.
The HALT mode release condition can be specified by the operand for the HALT instruction, as shown in Table
9-1.
After the HALT mode has been released, the operation is performed as shown in Table 9-2 and Figure 9-1.
Caution Do not execute an instruction that clears the interrupt request flag (IRQ
×××
) for which the
interrupt enable flag (IP
×××
) is set immediately before the HALT 8H instruction; otherwise, the
HALT mode may not be set.

Setting prohibited
Note
Set the clear level by using bits 0 to 2 (P1AHL0 to P1AHL2) of the register file at address 05H, and bit 2
(P1BHL0) at address 15H.
