NXP Semiconductors MPC5606S - LCD Bias and Modes of Operation

LCD Driver (LCD64F6B)
MPC5606S Microcontroller Reference Manual, Rev. 7
816 Freescale Semiconductor
Examples:
1. 40 (n=40) Frontplanes and 4 (m=4) backplanes are implemented. LCDBPS is set to 000 and
LCDBPA is set to 1
Frontplanes FP[39:2] and BP[3:0] will stay the same, but FP[1:0] pins will controlled by BP[5:4]
functionality.
2. 40 (n=40) Frontplanes and 4 (m=4) backplanes are implemented. LCDBPS is set to 010 and
LCDBPA is set to 0
Frontplanes FP[39:16] and FP[11:0] will stay the same, but FP[15:12] pins are swapped with
BP[3:0].
3. 40 (n=40) Frontplanes and 4 (m=4) backplanes are implemented. LCDBPS is set to 010 and
LCDBPA is set to 1
Frontplanes FP[39:18] and FP[11:0] will stay the same. FP[15:12] pins are swapped with BP[3:0].
FP[17:16] is replaced by BP[5:4] functionality.
4. 40 (n=40) Frontplanes and 4 (m=4) backplanes are implemented. LCDBPS is set to 101 and
LCDBPA is set to 1
No remapping: Frontplanes FP[39:0] and BP[3:0] will stay the same, because condition n>=44 is
not fulfilled.
22.5.7 LCD bias and modes of operation
The LCD64F6B driver has seven modes of operation:
• 1/1 Duty (1 backplane), 1/1 Bias (2 voltage levels)
