63 / 86 page  Electrical and Thermal Characteristics MPC5121E/MPC5123 Data Sheet, Rev. 4 Freescale Semiconductor 63 The DELTA_X and DELTA_Y parameters are programmed via the DISP_SIZE register; The PW_H, BP_H, and FP_H parameters are programmed via the HSYN_PARA register; And the PW_V, BP_V and FP_V parameters are programmed via the VSYN_PARA register. See appropriate section in the reference manual for detailed descriptions on these parameters. Figure 44 shows the synchronous display interface timing for access level, and Table 38 lists the timing parameters. Figure 44.
