Fig 19. Host Interface selection - I2C mode
In case that external host needs to be connected to the PN7462 over I²C interface then
corresponding I²C interface lines can be accessed directly on the JP32 according the
Table 3 and additional jumper configuration is not needed.
3.2.1.3 SPI Host Interface configuration
The yellow marked jumpers (Fig 20) needs to be set for using the SPI host interface of
the chip. This will connect the SPI_MOSI of the PN7462AU to the I/O P0(18), SPI_MISO
to the I/O P0(17), SCK to the I/O P0(15), and also the NSS of the PN7642AU to the I/O
P0(16) of the LPCXpresso board.
