Abstract: A flash memory controller is operative to receive serial commands and command arguments. A flash permissions table identifies each segment of flash memory as READ_ONLY, PRIVATE_R/W or OPEN_R/W. A memory interface is coupled to a flash memory and also the flash permissions table. When a flash memory write operation is received with an associated command argument corresponding to an address indicated as READ_ONLY in the flash permissions table and a DISABLE_WR_REG is true, the write operation is ignored or converted into a non-write command and issued to the flash memory.

Abstract: Systems and methods for reducing power consumption by using adaptive transmit power during sniff intervals are disclosed. The central device transmits the first packet of the sniff interval using the previously negotiated transmit power. After the central device receives a response from the peripheral device, the central device uses a lower transmit power for subsequent POLL packets during that sniff interval. This scheme may reduce the power consumption of the central device significantly, especially when a large number of packets are transmitted during each sniff interval.
