SUBH
Operation
RD – IMM8:$00
Subtracts a signed immediate 8 bit constant from the content of high byte of register RD and using binary
subtraction and stores the result in the high byte of destination register RD. This instruction can be used
after an SUBL for a 16 bit immediate subtraction.

Set if bit 15 of the result is set; cleared otherwise.
Set if the result is $0000; cleared otherwise.
Set if a two´s complement overflow resulted from the operation; cleared otherwise.
