Plane n Blinking Time Register (PnBTR) (n
= 1 to 6)
The plane n blinking time registers (PnBTR, n = 1 to 6) set the display interval length for plane n.
When the PnBM bit in PnMR is set to the auto display change mode (blinking mode), by setting,
in this register, the length of the interval of display of PnDSA0R and PnDSA1R, blinking
operation is performed using PnDSA0R and PnDSA1R.
When 1 is set, PnDSA0R and PnDSA1R are switched for each field.
When 0 is set, operation is the same as when set to 1.
