nRF24LE1 Preliminary Product Specification
The MCU system is configured with one serial port that is identical in operation to the standard 8051 serial
port (Serial interface 0). The two serial port signals RXD and TXD are available on device pins UART/RSD
and UART/TXD
The serial port (UART) derives its clock from the MCU clock; ckCpu. See
more information.

The serial port is controlled by S0CON , while the actual data transferred is read or written in the S0BUF
register. Transmission speed (“baud rate”) is selected using the S0RELL , S0RELH and ADCON registers.
