2 Module interfaces
2.2 Pin denition
The de󰍓nitions of pins are shown in the following table:
Pin number Symbol Pin type Function
1 P3 I/O Common I/O
interface, which
can be used as
SCK of the SPI
interface and
corresponds to P3
of the IC chip
2 P7 I/O Common I/O pin,
which can be used
as MOSI of the SPI
interface and
corresponds to P7
of the IC
3 P15 I/O Common I/O
interface, which
corresponds to
P15 of the IC chip
4 P16 I/O Common I/O
interface, which
corresponds to
P16 of the IC chip
5 P11 I/O ADC port, 12 bit/s,
which can also be
used as a common
I/O pin and
corresponds to
P11 of the IC chip
