LC88FC3K0A
 Infrared Remote Controller Receiver Circuit
1) Noise rejection function (noise filter time constant: Approx. 120s when the 32.768kHz crystal oscillator
is selected as the reference clock source)
2) Supports data encording systems such as PPM (Pulse Position Modulation) and Manchester encording
3) X’tal HOLD mode release function
 Internal Reset Function
 _{Power-on reset (POR) function}
1) POR reset is generated only at power-on time.
2) The POR release level can be selected through option configuration.
 _{Low-voltage detection reset (LVD) function}
1) LVD and POR functions are combined to generate resets when power is turned on and when power
voltage falls below a certain level.
2) The use/disuse of the LVD function and the low voltage threshold level can be selected by option
configuration.
 Interrupts (peripheral function)
 _{61 sources (33 modules), 14 vector addresses}
<1> Provides three levels (low (L), high (H), and highest (X)) of multiplex interrupt control. Any interrupt
requests of the level equal to or lower than the current interrupt are not accepted.
<2> When interrupt requests to two or more vector addresses occur at the same time, the interrupt of the
highest level takes precedence over the other interrupts. For interrupts of the same level, the interrupt
into the smallest vector address takes precedence.

 3 priority levels selectable
 Of interrupts of the same level, the one with the smallest vector address takes precedence.
 A number enclosed in parentheses denotes the number of sources.
 Subroutine stack : RAM area
 _{Subroutine calls that automatically save PSW, interrupt vector calls: 6 bytes}
 _{Subroutine calls that do not automatically save PSW: 4 bytes}
 Multiplication/division instructions
 _{16 bits × 16 bits (4 tCYC execution time)}
 _{16 bits ÷ 16 bits (18 to 19 tCYC execution time)}
 _{32 bits ÷ 16 bits (18 to 19 tCYC execution time)}
