9.15 Type A PCD
This paragraph explains how to realize a PN544 and its host(s) can be a Type A reader.
9.15.1 Type A PCD over SWP (UICC as a Type A reader)
The UICC can run a Type A reader application, as described in HCI specification.
Refer to paragraph SWP.
9.15.2 Type A PCD over host link (I2C, SPI, HSU) (Host as a Type A reader)
The host processor can run a Type A reader application, as described in HCI
specification.
Refer to paragraph Polling Loop (host reader example).
9.15.3 Meaning of additional commands of Reader RF gates for Type A
Refer to Reader RF gates additional commands chapter for commands description.
9.15.3.1 Several Type A cards in the RF field: use
NXP_WR_ACTIVATE_NEXT,
NXP_WR_ACTIVATE_ID
When there is several Type A cards in the field, the PN544 can send
NXP_WR_ACTIVATE_NEXT to put in HALT the first card detected and activate the other
card in the field (Fig 69).
To rea
ctivate a chosen card, its UID is used, in NXP_WR_ACTIVATE_ID command (Fig
70)
