Fig. 82. Structure of window L registers

Fig. 81. Structure of window H registers

Window L register 1

(WL1 : address 021D )

Control bits of window bottom boundary (Note)

Bottom boundary position (low-order 8bits)

TH!(setting value of low-order 2bits of

WL2!16 +setting value of high-order

4bits of WL1!16 +setting value of

low-order 4bits of WL1 !16 )

Window L register 2

(WL2 : address 021F )

Control bits of window bottom boundary (Note)

Bottom boundary position (high-order 2bits)

TH!(setting value of low-order 2bits of

WL2!16 +setting value of high-order

4bits of WL1!16 +setting value of

low-order 4bits of WL1!16 )

Note : Set values fit for the following condition : (WH1+WH2)

< (WL1+WL2).

Window H register 1

(WH1 : address 021C )

Control bits of window top boundary (Note)

Top boundary position (low-order 8bits)

TH!(setting value of low-order 2bits of

WH2!16 +setting value of high-order

4bits of WH1!16 +setting value of

low-order 4bits of WH1 !16 )

Window H register 2

(WH2 : address 021E )

Control bits of window top boundary (Note)

Top boundary position (high-order 2bits)

TH!(setting value of low-order 2bits of

WH2!16 +setting value of high-order

4bits of WH1!16 +setting value of

low-order 4bits of WH1 !16 )

Note : Set values except “00 16” and “0116” to the WH1 when the WH2 is “00 16.”
