SPI communication issue for Sharp memory LCD LS013B7DH03

We are finding issues with the SPI communication for LS013B7DH03 Sharp memory LCD using the K53 free scale micro controller. If someone have the library files for displaying kindly share with us. We couldn't exactly guess out where the Problem is ;either with the hardware or software. In case if the problem is with software or library files we guess it might be with the Timing error in CS chip select.

My tought (several days) that my ST7565P lcd was broken before I found from the web the working wait values to put before and after spi.write.

_cs = 0; wait_us(10); _spi.write(dat); wait_us(10); _cs = 1;

Some code in this site is for slower microcontrollers and needs modification for faster devices.
