Part Number: TMS320F28377S
Other Parts Discussed in Thread: CONTROLSUITE
Hi al,
The following two ISRs have different PIEACK clearing methods.
Which method is recommended (1) or (2)?
(1) C:\ti\controlSUITE\device_support\F2837xS\v210\F2837xS_examples_Cpu1\usb_dev_bulk\cpu01\usb_dev_bulk.c
__interrupt void
SysTickIntHandler(void)
{
//
// Update our system tick counter.
//
g_ui32SysTickCount++;
PieCtrlRegs.PIEACK.all |= 1;
}
(2) C:\ti\controlSUITE\device_support\F2837xS\v210\F2837xS_examples_Cpu1\watchdog\cpu01\watchdog_cpu01.c
__interrupt void wakeint_isr(void)
{
WakeCount++;
//
// Acknowledge this interrupt to get more from group 1
//
PieCtrlRegs.PIEACK.all = PIEACK_GROUP1;
}
Best regards,
Sasaki
