The buffer memory in the ISP1362 can be addressed using either the direct addressing
method or the indirect addressing method.
This method uses the HcDirectAddressLength register to specify two parameters required
to randomly access the ISP1362 buffer memory (total of 4096 bytes). These two
parameters are:
Starting address — location to start writing or reading
Data length — number of bytes to write or read
The following is a sample code to set the HcDirectAddressLength register:
result = result_h;
result = result<<16;
result = result+result_l;
return(result);
unsigned int low_word;
unsigned int hi_word;
low_word=data2write&0x0000FFFF;
hi_word=(data2write&0xFFFF0000)>>16;
outport(hc_com,reg_no|0x80); // Command phase
outport(hc_data,low_word); // Data phase
outport(hc_data,hi_word); // Data phase
unsigned int result;
outport(hc_com, reg_no); // Command phase
result = inport(hc_data); // Data phase
return(result);
outport(hc_com,reg_no|0x80); // Command phase
outport(hc_data,data2write); // Data phase
