8.2.2 Passive Communication mode

Passive Communication mode means that the target answers to an initiator command in a

load modulation scheme. The initiator is active meaning generating the RF field.

The contactless UART of PN511 and a dedicated host controller are required to handle

the NFCIP-1 protocol.

Note: Transfer Speeds above 424 kbit/s are not defined in the NFCIP-1 standard. The

PN511 supports these transfer speeds only with dedicated external circuits.
