Parameters:
slh Synchronous LIOX handle
cptMask Bit mask indicating which components should be configured
Returns:
0 on success, -1 on failure
1) cptMask is the concatenation of registers 4-6 of the EBM controller block (LAT-TD-01546, the source enable registers) with an additional bit in the most- significant-byte representing the SSR

unsigned int createSLH (  LCB  lcb,
LIOXs *  slh
) 
 

Allocate memory for and initializes Synchronous LIOX handle.

Parameters:
lcb Initialized LCB handle
slh Pointer to uninitialed Synchronous LIOX handle

LCB_cfg *  cfg
)

void powerOn (  LIOXs  slh,
unsigned  priMask,

Configures the PDUs to power the required components of the LAT.

void powerOn (LIOXs slh, unsigned priMask, unsigned redMask, unsigned delay)

Parameters:
slh Synchronous LIOX handle
priMask Bit mask indicating which components should be powered on by the PRIMARY PDU
redMask Bit mask indicating which components should be powered on by the REDUNDANT PDU
delay Time (in 60ths of a second) to wait after powering a cpt before powering the next
1) Function assumes that the CRU is unconfigured so begins by configuring the CRU to access the requested PDUs and sets the LATp addresses of the aforementioned PDUs.

2) Currently only the Primary EPU DC-DC converters are available.

3) Currently only the Primary ACD supply and converters are available.

4) priMask and redMask are laid out in the manner of the CRU command and response enable bit masks (LAT-TD-01547, figs 12 & 13).
