![]() There are multiple devices in the Texas Instruments MSP430 family of ultra-low-power microcontrollers, each of which has a unique set of peripherals designed for a particular purpose. Therefore, the return instructions do not need the modification of the PCLATH4:3> bits (which POPs the address from the stack) ![]() The full 13-bit PC is popped off the stack whenever a return from a CALL instruction (or interrupt) is performed. The user must make sure that the page choose bits are set when performing a CALL or GOTO instruction in order for the chosen programme memory page to be addressed. PCLATH4:3> provides the upper 2 bits of the address when performing a CALL or GOTO instruction. Only 11 bits of address are provided by the CALL and GOTO instructions, allowing branching inside any 2K programme memory page. On 28-pin devices, the Parallel Slave Port is not implemented.Įach PIC16F87X device has the ability to access an 8K word block of programme memory continuously. ![]() Devices for the PIC16F876/873 and PIC16F877/874 available in 28-pin and 40-pin packages, respectively. The PIC16F873, PIC16F874, PIC16F876 and PIC16F877 are the four covered devices. ![]()
