The 12 timestamp unit interrupts are ORed together (if enabled) to produce one
interrupt. Therefore the 12 TSUs produce only one interrupt, see
page 3-12
All the interrupt status bits are ‘sticky’ bits and can only be cleared by writing a ‘1’ to
the relevant interrupt clear register. The GPIO status MMIO register,
VIC_INT_STATUS
TSU caused the interrupt.
Any of the GPIO pins or internal signals can be selected as a timer source for
TM5250, see
TIMER_IO_SEL MMIO register, see
An interrupt called ‘gpio_interrupt’ is generated whenever the GPIO module requests
an interrupt. This event is a ‘wake-up’ interrupt for the clock module to turn back on
the system clocks once the PNX17xx Series has been sent into deep sleep mode.
Any of the GPIO pin can be used in case of an external watchdog style reset
generator as the output which is pulsed regularly by software to keep a reset from
occurring. WDOG_OUT pin is a regular GPIO pin without any special properties, and
can be used as an extra GPIO if no watchdog reset is present.
For each FIFO queue programmed in signal monitoring or pattern generation modes,
it is possible to divide the 108 MHz clock to obtain suitable frequencies for Ir
applications.
As well as the 16-bit divider to divide the 108 MHz clock, each FIFO queue has a
further 5-bit divider which can be enabled if sub-carrier frequencies are required for
transmission. Therefore, in Ir applications, a FIFO queue can produce Ir signals at a
a
for SOURCE number allocation.
