Abstract

A radio frequency programmable selective call receiver (100) provides a received signal having a recovered address, a command code, and a programming field. A decoder determines selection of the selective call receiver in response to correlating the recovered address (403) with a predetermined address stored in a non-volatile memory (107) that includes a plurality of registers for storing a plurality of configuration words which determine operational characteristics of the selective call receiver (100). A controller (105) selects and executes a bulk programming mode (1004) when a recovered data word (503) is unmasked, or a selective programming mode (1008, 1009, 1010, 1011, 1012) when the recovered data word (503) is masked. The bulk programming mode modifies at least one programmable option of the selective call receiver (100) by re-writing all programmable options in the range of a plurality of registers with data included in the unmasked data word. The selective programming mode modifies at least one programmable option of the selective call receiver (100) be re-writing only a specified register, thus changing only the selected at least one programmable option and preserving any other options in the specified register.
