Window H register 2
(WH2 : address 021E16)
Control bits of window top boundary (Note)
Top boundary position (high-order 2bits)
TH!(setting value of low-order 2bits of
WH2 !162 + setting value of high-order
4bits of WH1!16¹ + setting value of
low-order 4bits of WH1!16⁰)
Note : Set values except “0016” and “0116” to the WH1 when the WH2 is “0016.”

Window L register 2
(WL2 : address 021F16)
Control bits of window bottom boundary (Note)
Bottom boundary position (high-order 2bits)
TH!(setting value of low-order 2bits of
WL2!16²+ setting value of high-order
