Product data sheet
10.3.1 Connection to a host controller
10.3 UART interface
Write data:
To write data to the PN512 using the SPI interface the following byte order has to be used.
It is possible to write out up to n-data bytes by only sending one’s address byte.
The first send byte defines both, the mode itself and the address byte.
Note: The most significant bit (MSB) has to be send first.
Table 141. Byte order for MOSI and MISO
Address byte:
The address byte has to fulfill the following format. The MSB bit of the first byte defines
the used mode. To read data from the PN512 the MSB bit is set to logic 1. To write data to
the PN512 the MSB bit has to be set to logic 0. The bits 6 to 1 define the address and the
last bit shall be set to logic 0.
