CPCH
Operation
RS.H - IMM8 - C
Subtracts the carry bit and the 8 bit constant IMM8 contained in the instruction code from the high byte of
the source register RD using binary subtraction and updates the condition code register accordingly. The
carry bit and Zero bits are taken into account to allow a 16 bit compare in the form of
Remark: There is no equivalent operation using triadic addressing. Comparing the values of two registers
can be performed by using the subtract instruction with R0 as destination register.
