INTERNAL INTERFACE AD CONVERTER AND
TRANSCEIVER
8.1
P2 - Radio General Purpose IO Port
The P2 port controls the transceiver. The P2 port uses the address normally used by port
P2 in standard 8051. However since the radio transceiver is on chip, the port is not bi-
directional. The power on default values in the port “l(fā)atch” also differs from traditional
8051 to match the requirements of the radio transceiver subsystem.
Operation of the transceiver is controlled by SFR registers P2 and SPI_CTRL:

Table 14 nRF905 433/868/915 MHz transceiver subsystem control registers - SFR 0xA0
and 0xB3.
The bits of the P2 register correspond to similar pins of the nRF905 single chip, as
shown in Table 15 P2 (RADIO) register . In the documentation the pin names are used,
so please note that setting or reading any of these nRF905 pins, means to write or read
the P2 SFR register accordingly.
