CKSEL1

Clock source selection for counter/timer 1:

 

 

 

 

0

= internal oscillator, frequency selected by CLKFRQ1

 

 

 

1

= external clock input CLK1 (DIO C pins must be set for ctr/timer signals)

CKFRQ1

Input frequency selection for counter/timer 1 when CKSEL1 = 1:

 

 

0

= 10MHz, 1 = 100KHz

 

 

 

 

 

 

 

CKFRQ0

Input frequency selection for counter/timer 0.

 

 

 

 

0

= 10MHz, 1 = 1MHz

 

 

 

 

 

 

 

ADCLK

A/D trigger select when AINTE = 1:

 

 

 

 

 

 

0

= internal clock output from counter/timer 0

 

 

 

 

1

= external clock input EXTTRIG

 

 

 

 

 

DMAEN

Enable DMA operation. 1 = enable, 0 = disable.

 

 

 

TINTE

Enable timer interrupts. 1 = enable, 0 = disable.

 

 

 

DINTE

Enable digital I/O interrupts. 1 = enable, 0 = disable.

 

 

 

AINTE

Enable analog input interrupts. 1 = enable, 0 = disable.

 

 

 

NOTE: When AINTE = 1, the A/D cannot be triggered by writing to Base + 0.

Analog output interrupts are not supported on this board.

Multiple interrupt operations may be performed simultaneously. All interrupts will be on the same interrupt level. The user’s interrupt routine must monitor the status bits to know which circuit has requested service. After processing the data but before exiting, the interrupt routine must then clear the appropriate interrupt request bit using the register at Base + 0.

FIFO threshold. When the number of A/D samples in the FIFO reaches this number,

 

the board will generate an interrupt and set AINT high (Base + 7 bit 4). The interrupt

 

routine is responsible for reading the correct number of samples out of the FIFO.

The valid range is 1-48. If the value written is greater than 48, then 48 will be used. If the value written is 0, then 1 will be used. The interrupt rate is equal to the total sample rate divided by the FIFO threshold. Generally, for higher sampling rates a higher threshold should be used to reduce the interrupt rate. However remember that the higher the FIFO threshold, the smaller the amount of FIFO space remaining to store data while waiting for the interrupt routine to respond. If you get a FIFO overflow condition, you must lower the FIFO threshold and/or lower the A/D sampling rate.
