6.5 XferInstruction Pseudo
Operation
Format:
XferInstruction (instruction)
Purpose:
To send 32 bits of data for the device to execute.
Description:
The instruction is clocked into the device and then
executed by CPU.
Restrictions:
The device must be in Debug mode.
EXAMPLE 6-2: XferInstruction
XferInstruction (instruction)
{
// Select Control Register
SendCommand(ETAP_CONTROL);
// Wait until CPU is ready
// Check if Processor Access bit (bit 18) is set
do {
controlVal = XferData(32’h0x0004C000);
} while( PrAcc(contorlVal<18>) is not ‘1’ );
// Select Data Register
SendCommand(ETAP_DATA);
// Send the instruction
XferData(instruction);
// Tell CPU to execute instruction
SendCommand(ETAP_CONTROL);
XferData(32’h0x0000C000);
}
