CHAPTER 22 LOW-VOLTAGE DETECTOR

Preliminary User’s Manual U16315EJ1V0UD

372

(1) Low-voltage detection register (LVIM)

This register sets low-voltage detection and the operation mode.

This register can be set by a 1-bit or 8-bit memory manipulation instruction.

RESET input clears LVIM to 00H.

Figure 22-2. Format of Low-Voltage Detection Register (LVIM)

LVIF

LVIMD

LVIE

LVION

Symbol

LVIM

Address: FFBEH After reset: 00H R/W

Note 1

LVION

Notes 2, 3

Enables low-voltage detection operation

Disables operation

Enables operation

LVIE

Notes 2, 4, 5

Specifies reference voltage generator

Disables operation

Enables operation

LVIMD

Note 2

Low-voltage detection operation mode selection

Generates interrupt signal when supply voltage (V

) < detection voltage (V

LVI

)

Generates internal reset signal when supply voltage (V

) < detection voltage (V

LVI

)

LVIF

Note 6

Low-voltage detection flag

Supply voltage (V

) > detection voltage (V

LVI

), or when operation is disabled

Supply voltage (V

) < detection voltage (V

LVI

)

Notes 1.

Bit 0 is read-only.

LVION, LVIE, and LVIMD are cleared to 0 at a reset other than an LVI reset. These are not

cleared to 0 at an LVI reset.

When LVION is set to 1, operation of the comparator in the LVI circuit is started. Use

software to instigate a wait of at least 0.2 ms from when LVION is set to 1 until the voltage is

confirmed at LVIF.

When LVIE is set to 1, a reference voltage generator operation in the LVI circuit is started.

Use software to instigate a wait of at least 2 ms from when LVIE is set to 1 until LVION is set

to 1.

If “use POC” is selected by a mask option, leave LVIE as 0. A wait time (2 ms) until LVION is

set to 1 is not necessary.

The value of LVIF is output as the interrupt request signal INTLVI when LVION = 1 and

LVIMD = 0.

Caution

To stop LVI, follow either of the procedures below.

••••

When using 8-bit manipulation instruction: Write 00H to LVIM.

••••

When using 1-bit memory manipulation instruction: Clear LVION to 0 first and then

clear LVIE to 0.
