Function Documentation

void getCruState ( PIG_cruState *  state  ) 

Get the saved copy of the contents of the CRU registers.

Parameters:
state Pointer to a structure to receive the state of the CRU registers

void getDbState ( PIG_dbState *  state  ) 

Get the saved copy of the contents of the database registers.

Parameters:
state Pointer to a structure to receive the state of the database registers

void getEbmState ( PIG_ebmState *  state  ) 

Get the saved copy of the contents of the EBM registers.

Parameters:
state Pointer to a structure to receive the state of the EBM registers

void getPduState ( PIG_pduState *  state  ) 

Get the saved copy of the contents of the PDU registers.

Parameters:
state Pointer to a structure to receive the state of the PDU registers

void getPwrState ( PIG_pwrState *  state  ) 

Get the saved copy of the contents of the power registers.

Parameters:
state Pointer to a structure to receive the state of the power registers

void getState ( PIG_state *  state  ) 

Get a copy of the state of all PIG registers.

Parameters:
state Pointer to a structure to receive the state of the PIG registers

unsigned int PIG_get_ebmState ( unsigned int *  inputs,
unsigned int *  contbs,
unsigned int *  destns 
)

Return the EBM configuration masks.

Parameters:
inputs Address of an integer to receive the source processor input enables, or NULL if this value is not wanted.
contbs Address of an integer to receive the EBM scheduler contributor enables, or NULL if this value is not wanted.
destns Address of an integer to receive the round-robin and broadcast masks, or NULL if this value is not wanted.
Return values:
PIG_INMUD Success

unsigned PIG_verify ( void   ) 

Verify the PIG state.

This routine reads all the PIG-controlled registers and compares their values with the cached ones.

Return values:
PIG_INMUD Register values all matched.
PIG_VERFAIL0 A single-occurrence register value didn't match.
PIG_VERFAIL1 A PDU, TEM or ARC register value didn't match.
PIG_VERFAIL2 A CCC or TCC register value didn't match.

unsigned readCruState ( LEM_micr *  cr,
PIG_cruState *  state 
)

Take a snapshot of the state of the CRU.

Parameters:
cr Pointer to a multi-item command and response list
state Pointer to a structure to receive the state of the CRU registers

unsigned readDbState ( LEM_micr *  cr,
