Table 9-2.
Operations After HALT Mode Release
(a) HALT 08H
HALT Mode Released by:
Interrupt Status
Interrupt Enable Flag
Operations After HALT Mode Release
When release condition of P0A0
Don’t care
Instruction next to HALT is executed
to P0A3, P0B0 to P0B3, P0C0 to
P0C3, P0D0 to P0D3, P0E0 to P0E3,
P1A0 to P1A2, P1B0 is satisfied
When release condition is
DI
Disabled
Standby mode is not released
satisfied by interrupt request
Enabled
Instruction next to HALT is executed
EI
Disabled
Standby mode is not released
Enabled
Branches to interrupt vector address
(b) HALT 02H
HALT Mode Released by:
Interrupt Status
Interrupt Enable Flag
Operations After HALT Mode Release
8-bit timer
DI
Disabled
Instructions are executed from the
Enabled
instruction next to the HALT instruction.
EI
Disabled
Enabled
Branches to interrupt vector address
9.2
HALT Instruction Execution Conditions
The HALT instruction can be executed under special conditions, as shown in Table 9-3, to prevent the program
from hanging up.
If the conditions in Table 9-3 are not satisfied, the HALT instruction is treated as a NOP instruction.
Table 9-3.
HALT Instruction Execution Conditions
Operand Value
Execution Conditions
0010B (02H)
When all interrupt request flags (IRQTM) of 8-bit timer are reset
1000B (08H)
<1> When interrupt request flag (IRQTH, IRQBTM, or IRQ) is reset, corresponding to interrupt whose
interrupt enable flag (IPTM, IPBTM, or IP) is set
<2> When high level is input to all P0A0 to P0A3 pins
<3> When P0B0 to P0B3, P0C0 to P0C3, and P0D0 to P0D3 are used as input pins, a high level must
be input to all the pins.
<4> A high level must be input to all the pins if P0E0 to P0E3 are used as input pins when a key
matrix is used.
<5> A level reverse to the set clear levelNote must be input to all the pins if P1A0 to P1A2 and P1B0
are used as input pins when a key matrix is used (for example, if the clear level is high, the
execution condition is low-level input).
Other than above
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.
