32-bit ARM Cortex-M3 microcontroller
P0[22]/RTS1/TD1 44
[1]
I/O P0[22] — General purpose digital input/output pin.
O RTS1 — Request to Send output for UART1. Can also be configured to be an
RS-485/EIA-485 output enable signal.
O TD1 — CAN1 transmitter output.
P0[25]/AD0[2]/
I2SRX _SDA/
TXD3
7
[2]
I/O P0[25] — General purpose digital input/output pin.
