MPC823 ELECTRICAL SPECIFICATIONS

Tcyc is the cycle time of the LCD clock (shift clock). Tdelay is a circuit delay that is specified in
the AC electrical specifications. 116 lines is a time period that can vary between one scan line
and 16, depending on how the LCD controller is programmed in the VPW field of the LCVCR.
01,023 lines is a time period that can vary between 0 and 1,023 scan lines in the WBF field of
the LCVCR.

NOTES:
1.
T = shift clock cycle (220).
2.
This number is given for wbl(wait between lines)
2. For wbl=n {n>2} the timing will be (n+2)T.
3.
This number is given for wbl(wait between lines)
2. For wbl=n {n>2} the timing will be (n+2)T.
4.
Wait Between Frames (WBF) is a programmable parameter.
