SWITCH FOR DATA
(1)
Pull-down resistor
When 0...Not provided (OFF)
When 1...Provided (ON)
(2)
Modulation duty (at f
OSC
/12)
When 0...1/2 duty
When 1...1/3 duty
(3)
Hang-up detection
<1> K
I/O
ALL
If the switch for hang-up detection K
I/O
ALL is set to ON (1) by mask option, the system is reset if, in oscillation
HALT (STOP) mode, the K
I/O
pin is in input mode, or if at least one of the K
I/O
pins is low (AC pin discharge
mode).
When 0...No reset function (OFF)
When 1...Reset function (ON)
Caution
To use a pin as a key source of a key matrix, be sure to set the switch to ON by mask option.

)
If the condition specified by mask option to be unused is satisfied in the HALT mode, the system is reset.
When 0...Used
When 1...Unused
Caution
Be sure to specify the HALT mode of the unused releasing condition to be unused (set).
