7 ^{(RB10 to RB17)}
Functions
Right border position (low-order 8 bits)
TOSC !
(setting value of low-order 3 bits of RB2 ! 16²
+ setting value of high-order 4 bits of RB1 ! 16¹
+ setting value of low-order 4 bits of RB1 ! 16⁰)

1 RW
Notes 1: Set values fit for the following condition:
(LB1 + LB2 ! 16²) < (RB1 + RB2 ! 16²).
2: TOSC is OSD oscillation period.
3: RB2 is right border control register 2.
