STPD
STPD is a bit to change the operating state into the STOP-D mode. When "1" is written in the
STPD bit after entering the STOP mode is allowed by using STPACP, the operating state
enters the STOP-D mode.
When an external interrupt enabled in the interrupt enable registers (IE0 to IE7) is generated,
the STOP-D mode gets canceled and returns to program run mode.
2
HLTH
HLTH is a bit to stop forcibly the high-speed oscillation and change the operating state into
the HALT-H mode.
When the WDT interrupt or an interrupt enabled in the interrupt enable registers (IE0 to IE7)
is generated, the HLTH mode gets canceled and returns to program run mode after enabling
the high-speed oscillations forcibly.
1
STP
STP is a bit to change the operating state into the STOP mode. When "1" is written in the
STP bit after entering the STOP mode is allowed by using STPACP, the operating state
enters the STOP mode.
When an external interrupt enabled in the interrupt enable registers (IE0 to IE7) is generated,
the STOP mode gets canceled and returns to program run mode.
0
HLT
HLT is a bit to change the operating state into the HALT mode.
When the WDT interrupt or an interrupt enabled in the interrupt enable registers (IE0 to IE7)
is generated, the HALT mode gets canceled and returns to program run mode.
[Note]
Ÿ
The operating state does not enter the standby mode under the condition that both an interrupt enable
flag and an interrupt request flag are
"
1" that is requesting the interrupt to the CPU.
Ÿ
When an interrupt enabled in the interrupt enable registers (IE0 to IE7) is generated on the condtion of
MIE flag of the program status word (PSW) is "0", it cancels the standby mode only and the CPU does
not go to the interrupt routine. For more details about MIE flag, see "nX-U16/100 Core Instruction
Manual".
Ÿ
Insert two NOP instructions in the next to the instruction of that sets HLT, STP, HLTH and STPD bit to "1".
The operation without the two NOP instructions is not guaranteed.
Ÿ
If two bits or more in the SBYCON are set to "1" at the same time, the setting are gets invalid and
continues the program rum mode.
Ÿ
When the CPU operation mode is "Wait mode", the PLL reference frequency is 24MHz and the MIE bit is
"0", choose 12MHz or slower as the SYSTEMCLK before entering the standby modes.
Ÿ
When choosing the low-speed crystal oscillation clock or low-speed external clock (LOSCM[1:0] of
FLMOD register is set to "01" or "11"), switch the SYSTEMCLK to the low-speed clock before setting STP
bit or STPD bit.
