PHK (Push Program BanK) is a 65c816 instruction that pushes the value of the program bank register onto the stack. PHK always pushes a single byte. The stack pointer is decremented by one.
No flags are affected.
Syntax
PHK
Its PLK counterpart does not exist. PHK works even in emulation mode even though all bank addresses are forced to be zero.
