i have written that code for JHD 162A lcd display ...but in that code  i have wirtten  register instructions like GpioCtrlRegs.GPAMUX1.bit.GPIO6 = 0;,
GpioCtrlRegs.GPADIR.bit.GPIO6 = 1; for pins intiaization But when im compiling this code it shows errors like 

Description Resource Path Location Type
#20 identifier "GpioCtrlRegs" is undefined
#20 identifier "GpioDataRegs" is undefined 
#20 identifier "GpioDataRegs" is undefined
#20 identifier "GpioDataRegs" is undefined

#20 identifier "ragavendra" is undefined
gmake: *** [lcd displayyy.obj] Error 1 
gmake: Target 'all' not remade because of errors. led displayy C/C++ Problem

what is the reason behind that...it needs any header file for that?please correctt that code
