32-bit ARM Cortex-M3 microcontroller
P0[25] 14 F1 E4 10
[5]
I;
PU
I/O P0[25] — General purpose digital input/output pin.
I ADC0_IN[2] — A/D converter 0, input 2. When configured as an
ADC input, the digital function of the pin must be disabled.
I/O I2S_RX_SDA — Receive data. It is driven by the transmitter
and read by the receiver. Corresponds to the signal SD in the
I
2
S-bus specification.
O U3_TXD — Transmitter output for UART3.
