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 initializes all operational registers (32-bit). The
FSLargestDataPacket field (bits 30 to 16) of the HcFmInterval register (0DH - read,
8DH - write) and the HcLSThreshold register (11H - read, 91H - write) determine the
{
outport(HcDataPort,PTDData[i]);
};
wData = HcRegRead(wHcuPInterrupt);
printf("\n HC Interrupt Status = %xH.\n",wData);
wData = HcRegRead(wHcBufferStatus);
printf("\n HC Buffer Status = %xH.\n",wData);
}
{ unsigned int wValue;
outport(HcCmdPort,wIndex & 0x7f);
wValue = inport(HcDataPort);
return(wValue);
{
outport(HcCmdPort,wIndex | 0x80);
outport(HcDataPort,wValue);
}
