Bit 7~6
Unimplemented, read as "0"
Bit 5
NFCWA
:
NFC memory page address automatic increase for MCU write operation
control
0: Disable
1: Enable
This is the NFC memory page address automatic increase control bit which must be
set high before MCU write operations are carried out. Clearing this bit to zero will
inhibit the NFC memory
page address automatic increase for MCU write operations.
If the NFC page address reaches 0x4Fh, then the next page address will be 0x00h. If
the error interrupt request WIPF, RIPF or ERF occurs, the NFC memory page address
will not be increased.
Bit 4
NFCRA
:
NFC memory page address automatic increase for MCU read operation
control
0: Disable
1: Enable
This is the NFC memory page address automatic increase control bit which must be
set high before MCU read operations are carried out. Clearing this bit to zero will
inhibit the NFC memory
page address automatic increase for MCU read operations.
If
the NFC page address reaches 0x4Fh, then the next page address will be 0x00h. If an
error interrupt request WIPF, RIPF or ERF occurs, the NFC memory page address will
not be increased.
