Run results of the C program example
9.5 HC operational model
//write 80 (0x50) bytes of data into ATL buffer RAM
for (i 0;i<wCount;i
//Check EOT interrupt bit
//Check Buffer status register
//
// Read HC 16-bit registers
//
unsigned int HcRegRead(unsigned int wIndex)
}
//
// Write HC 16-bit registers
//
void HcRegWrite(unsigned int wIndex,unsigned int wValue)
Upon power up, the HCD sets up all operational registers (32-bit). The
FSLargestDataPacket field (bits 30 to 16) of the HcFmInterval register (0DH to read,
8DH to write) and the HcLSThreshold register (11H to read, 91H to write) determine
{
outport(HcDataPort,PTDData[i]);
};

}
{ unsigned int wValue;
outport(HcCmdPort,wIndex & 0x7f);

return(wValue);
{
outport(HcCmdPort,wIndex | 0x80);
outport(HcDataPort,wValue);
