Instruction Set www.ti.com
The specified pin action is performed as long as the count after count value is
decremented is greater than 0. The opposite pin action is performed when the
count after decrement just reaches 0.
If the hr_lr bit is reset, the opposite pin action will be taken after a HR delay
from the next loop resolution clock. If the hr_lr bit is set, the delay is ignored.
This delay is programmed in bits [D6:D0].
irq ON generates an interrupt when the data field value reaches 0. No
interrupt is generated for OFF.
Default: OFF.
data 25-bit integer value serving as a counter.
hr_data HR delay.
Default: 0.
Execution
If (Data field value == 0)
{
Selected register = 0;
Jump to Next Program Address;
}
If (Data field value > 1)
{
Selected register = Data field value - 1;
Data field value = Counter value - 1;
If (Enable Pin action == 1)
{
Selected Pin = Pin Action AT next loop resolution clock;
}
Jump to Next Program Address;
}
If (Data field value == 1)
{
Selected register = 0000000h;
Data field value = 0000000h;
If (Opposite action == 1)
{
If (hr_lr bit == 0)
{
If (Enable Pin action == 1)
{
Selected Pin = Opposite level of Pin Action AT next loop resolution clock
+ HR delay;
}
}
else
{
If (Enable Pin action == 1)
{
Selected Pin = Opposite level of Pin Action AT next loop
resolution clock;
}
}
If (Interrupt Enable == 1) HETFLG[n] = 1; /* n depends on address */
If ([C28:C27] == 01) Generate request on request line [P25:P23];
