Detailed Description

An (hardware layer) object for accessing/updating the Time Processing Unit (TPU) registers.

:

Remarks

The TPU prescaler is currently set in the constructor and, thus there is no way to change it. I will probably change this in a future release.

Using the Design Pattern terminology, the TPU is a singleton object. In short, that means you declare any number of TPU objects in different modules, but you will be accessing the same object (declared static).

Sample Code

#include <tpu.h>
#include <oconsole.h>
TPU mytpu;

int main()
{
oConsole console;
int i;
  i = mytpu.TCR1();
  console.echo("i=",i);
}

Member Function Documentation

bool CIER (  int  chan, int  cie )  [static]

Configures the channel interrupt enable register. Parameters: int:  channel int:  1 enables; 0 disables

bool CPR (  int  chan, int  val )  [static]

Configures the channel priority register (Ref. TPU Channel Utilization). Parameters: int:  channel int:  priority

bool HSQR (  int  chan, int  val )  [static]

Configures the host sequence register. Parameters: int:  channel int  dependent upon function (CFSR) selected

bool HSRR (  int  chan, int  val )  [static]

Configures the host sequence request register. Parameters: int:  channel int:  dependend upon function

int TCR1 (  void   )  [static]

misnomer--should be TCR1 divisor--return number of clocks (PSCK,TCR1P modifications) Globally available object. Can be used in combination with TPU_REGISTER definition to say TPU_REGISTER->CFSR.BITS...

void TMCR (  int  iarb  )  [static]

was tpu_init Configures the channel function select register
