14.34.8.6 INT
Function:
Interrupt.
Description: The
interrupt
IRQ_CSP_INT is asserted when this
instruction is executed.
Operation: IRQ_CSP_INT=1
Opcode:
76543210
10111001
flag IRQ_CSP_WT is asserted when the
wait condition is true.
Operation:
PC := PC while number of MAC Timer
overflow = true < W
PC := PC+1 when number of MAC Timer
overflow = true = W
Opcode:
76543210
100
W
14.34.8.7 WAITX
Function:
overflows
Wait for X MAC Timer
Description: Wait until MAC Timer
overflows the number of times equal to
register X. The contents of register X is
decremented each time a MAC Timer
overflow is detected. Program execution
continues with the next instruction and the
interrupt flag IRQ_CSP_WT is asserted
when the wait condition is true.
Operation:
X := X-1 when MAC Timer overflow = true
PC := PC while number of MAC Timer
overflow = true < X
PC := PC+1 when number of MAC Timer
overflow = true = X
Opcode:
76543210
10111011
14.34.8.9 WEVENT
Function:
compare
Wait until MAC Timer
Description: Wait until next MAC Timer
compare. Program execution continues
with the next instruction when the wait
condition is true.
Operation:
PC := PC while MAC Timer compare =
false
PC := PC+1 when MAC Timer compare =
true
Opcode:
76543210
10111000
14.34.8.8 WAIT W
Function:
overflows
Wait for W MAC Timer
Description: Wait until MAC Timer
overflows number of times equal to value
W. If W=0 the instruction will wait for 32
overflows. Program execution continues
with the next instruction and the interrupt
