(1)

If VCC rises to VSH (4.55V, 4.35V), the INT output is

set to high level.

*1. A pulse is output if

INT is of pulse output type.

RESET goes high td (s) after VSH.

*1. td ≈ 1.52 × 10

5 × C (s)

If VCC drops to VSL (4.45V, 4.25V), INT goes low.

*1. A pulse is output if

INT is of pulse output type.

*2. The

RESET output continues to be held high.

(3):

If VCC returns to VSH, the INT output is set to high level.

Same as (3).

If VCC becomes lower than VBATT (2.15V), the RESET

output is set to low thereby resetting the microcomputer

and initializing system.

Same as (1).

Same as (2).

Same as (3) and (5).

Same as (6).
