The 'XCHG' instruction in assembly language is used to exchange the values of two operands, typically a register and a memory location, effectively performing a swap without needing a temporary variable. It is significant for implementing atomic operations in multi-threaded programming. The 'SPHL' instruction, specific to certain assembly languages like 8085, is used to load the stack pointer (SP) with the address contained in the HL register pair, which is crucial for managing the stack in subroutine calls and local variable storage. Both instructions are fundamental for efficient low-level programming and system control.

XTHL and SPHL pair in 8085 microprocessor?
XTHL exchanges HL register with the content of the stack. XTHL followed by RET allows to return to an other address than the one which was previously pushed by a CALL. Eg.: ... CALL FOOBAR ... FOOBAR ... LXI, H @@@@ XTHL RET ;return to @@@@, not after the 'call' Alain FOUERE 22april2009

Why stax h not possible in 8085 microprocessor?
There is no STAX for HL register pair because the data transfer for STAX can be done through XCHG command. For ex: to transfer the data to the memory loaction specified by the HL pair we do as follows: XCHG STAX D for DE pair and BC pair we can directly do it using STAX
