Details of IC pin status as a result of executing the FLT instruction are shown in the above table.
(4) FLTT (floating of all output pins)
Instruction code :
Description :
Details of IC pin status as a result of executing the FLTT instruction are shown in above
Table.
Example 1 : Power-down mode accomplished by stopping oscillation.
m
Can be set by execution of HLTS [82H] instruction.
Example 2 : Power-down mode accomplished by stopping the clock supply to the CPU
control circuit.
m
Can be set by execution of HALT [01H] instruction.
Example 3 : Power-down mode by floating of P10-7, P20-7 and BP0-7, and subsequent
stopping of CPU oscillation.
m
Can be set by first executing the FLT [A2H] instruction, followed by the
HLTS [82H] instruction.
Example 4 : Power-down mode by floating P10-7, P20-7 and BP0-7, and then stopping the
clock supply to the CPU control circuit.
m
Can be set by first executing the FLT [A2H] instruction, and then the HALT
[01H] instruction.
Example 5 : Power-down mode by floating all output pins, followed by stopping oscillation.
m
Can be set by first executing the FLTT [C2H] instruction followed by
execution of the HLTS [82H] instruction.
Example 6 : Power-down mode by floating all output pins, followed by stopping of the
clock supply to the CPU control circuit.
m
Can be set by first executing the FLTT [C2H] instruction, followed by
execution of the HALT [01H] instruction. Connect the pull-up resistor or
pull-down resistor to port pin and fix the output port pin level to either 1or
0 when output port is set to floating.
