5.2 Standby Mode Setting and Release
The standby mode is set with the HALT #b3b2b1b0B instruction for both STOP mode and HALT mode. For the
standby mode to be set, the status flag (F) is required to have been cleared (to 0).
The standby mode is released by the release condition specified with the reset (POC) or the operand of HALT
instruction. If the standby mode is released, the status flag (F) is set (to 1).
Even when the HALT instruction is executed in the state that the status flag (F) has been set (to 1), the standby
mode is not set. If the release condition is not met at this time, the status flag is cleared (to 0). If the release condition
is met, the status flag remains set (to 1).
Even in the case when the release condition has been already met at the point that the HALT instruction is
executed, the standby mode is not set. Here, also, the status flag (F) is set (to 1).
Caution Depending on the status of the status flag (F), the HALT instruction may not be executed. Be
careful about this. For example, when setting HALT mode after checking the key status with
the STTS instruction, the system does not enter HALT mode as long as the status flag (F)
remains set (to 1) and thus sometimes performs an unintended operation. In this case, the
intended operation can be realized by executing the STTS instruction immediately after setting
the timer to clear (to 0) the status flag.
Example
STTS
#03H
;To check the KI pin status.
MOV
T, #0xxH
;To set the timer
STTS
#05H
;To clear the status flag
(During this time, be sure not to execute an instruction that may set the status flag.)
HALT
#05H
;To set HALT mode
