RADIO FREQUENCY FRONT END DEVICES WITH MASKED WRITE

摘要

Methods and apparatuses are described that facilitate the communication of data between a transmitter and a receiver across a serial bus interface. In one configuration, a transmitter generates a datagram based on a 16-bit address and a mask-and-data pair burst length, the 16-bit address including a most significant byte (MSB) and a least significant byte (LSB), compares the MSB to a receiver base address maintained in a shadow register, compares the mask-and-data pair burst length to a receiver masked-write burst length maintained in the shadow register, and sends the datagram to the receiver via the bus interface when: the MSB is equal to the receiver base address maintained in the shadow register, and the mask-and-data pair burst length is equal to the receiver masked-write burst length maintained in the shadow register.

主权项

1. A method performed at a transmitter for sending data to a receiver via a bus interface, comprising:
generating a datagram based on a 16-bit address and a mask-and-data pair burst length, the 16-bit address including a most significant byte (MSB) and a least significant byte (LSB); comparing the MSB to a receiver base address maintained in a shadow register; comparing the mask-and-data pair burst length to a receiver masked-write burst length maintained in the shadow register; and sending the datagram to the receiver via the bus interface when:
the MSB is equal to the receiver base address maintained in the shadow register, andthe mask-and-data pair burst length is equal to the receiver masked-write burst length maintained in the shadow register.
