When using the 20-pin ZLP32300P20xx, setting jumpers J3 and J4 IN and J6 and
J7 IN provide the maximum 7x6 key matrix for the 20-pin configuration with Stop
Mode Recovery supported.
The learning circuit on the LP32300 IR development platform consists of four
major components (refer to the schematic starting on page 18):

The photo current of photo detector D10 is summed with the feedback current of
operational amplifier U6A. The output signal is brought up to the TTL-compatible
level by low-pass filter U6B, and the resulting signal is delivered to the IR_IN
(P31) of U1 and U2. The circuit has been tested for 1.8V = Vbat = 3.6V, and for
frequencies 40KHz = F = 2MHz. The learning circuit is available only for 28- and
40-pin parts.

Serial EEPROM is not connected
Infrared receiver is not connected
IR LED is driven by resistor connection.
If 1 and 2 are IN, the IR LED is driven by a capacitor coupling.
Port 2 is connected to key matrix columns. P20 through P27 connect to
Columns 0 through 7, respectively.
Port 0 is connected to key matrix rows. P00 through P07 connect to Rows
0 through 7, respectively.
