6.8.10

INT_STAT

(R

EAD

/C

LEAR

)

Each bit cor

responds to an interrupt source. Reading a value of ‘1’ indicates that an event has occurred. Reading a value of ‘0’ indica

tes that

the event has not occurred. Writing a ‘1’ will clear that bit.

B0: Count

–

The count has changed.

B1: Interval Counter

–

Interval count has been reached

B2: Reserved
B3: Start Trigger
B4: Stop Trigger
B5: Reserved
B6: Reserved
B7: Reserved

6.8.11

CLK_BUS

N

Selects a source to drive onto Clock Bus N. That clock bus can then be used by a different function block as a clock source or trigger.

A function block can drive multiple different Clock Buses. However, a Clock Bus N should not be driven by more than one function block at the
same time or the clock signal will be undefined.

B[7:0]:

0x00: Disabled (Default)

0x80: Count

The count has changed.

o

0x81: Interval Counter

–

Interval count has been reached.

6.8.12

MODE_CONFIG

(MASKABLE

READ/WRITE)

This register provides configuration for Programmable Clock function block.

B[1]: Interval Count Reset: When enabled this causes the Count register to reset to 0 every interval clock pulse.

o

’0’ = Interval Count Reset is disabled

o

’1’ = Interval Count Reset is enabled

B[0]: Interval Counter Enable: Used to enable/disable the interval counter.

o

’0’ = Interval Counter is disabled

o

’1’ = Interval Counter is enabled

6.8.13

CH

N

_FIFO_DATA_CNT

(R

EAD

)

This register shows the current sample count that is available in the interval counter FIFO.

6.8.14

CH

N

_MAX_FIFO_SIZE

(R

EAD

)

This register shows the max number of samples that the interval counter FIFO can hold.

6.8.15

INTERVAL_CLK_DIV

(R

EAD

/W

RITE

)

Divider for the interval clock. Interval Clock Frequency = (System Clock) / (1 + INTERVAL_CLK_DIV). When the interval counter is enabled,
every interval clock pulse will update the LAST_INTERVAL_COUNT and generate an interval counter interrupt.

6.8.16

LAST_INTERVAL_COUNT

(R

EAD

-O

NLY

)

The last count value taken from the COUNT register. This is the same value that is written to the DMA FIFO.
