Infrared Preprocessor (IFR)
ST7FLCD1
84/95
The IFR input signal is preprocessed by a spike filter. This filter removes all pulses with a positive
level that lasts less than 2 μs or 160 μs, depending on the FLSEL bit. The negative level can be of
any duration and is never filtered out.
Note:
If the interrupt is enabled but no signal is detected, an interrupt occurs every 20.4 ms.

Register Description
INFRA RED DATA REGISTER (IFRDR)
Read/Write
Reset Value: (00h)
Bits [7:0] = IR[7:0]
Infra red pulse width
The 8-bit counter value is transferred in this register when an expected edge occurs on the IFR pin
or when the counter overflows. A write to this register resets the internal overflow flag.
INFRA RED CONTROL REGISTER (IFRCR)
Read/Write
Reset Value: (00h)
Bits [7:5] = Reserved.
Forced by hardware to 0.
Bit 4 = ITE
Interrupt enable
0
Interrupt disabled
1
Interrupt enabled. It is generated when an edge (falling and/or rising depending on bits POSED
and NEGED) occurs
or after a counter overflow.
Bit 3 = FLSEL
Spike filter pulse width selection
0
Filter positive pulses narrower than 2 μs
1
Filter positive pulses narrower than 160 μs
Bits [2:1] = POSED, NEGED
Edge selection for the duration measurement
Bit 0 = Reserved.
Forced by hardware to 0.
