BSP Organization
sysSerialHwInit( ) - initialize the BSP serial devices to a quiescent state
sysSerialHwInit2( ) - connect BSP serial device interrupts
sysSerialChanGet( ) - get the SIO_CHAN device associated with a serial
channel
sysToMonitor( ) - transfer control to the ROM monitor

2.2.4 Optional Routines
The following routines are usually present on all targets. Those marked as
“internal” are internal to the BSP and are not called by the application.
sysAbortInt( ) - handle the ABORT button interrupt
sysAuxClkConnect( ) - connect a routine to the auxiliary clock interrupt
sysAuxClkDisable( ) - turn off auxiliary clock interrupts
sysAuxClkEnable( ) - turn on auxiliary clock interrupts
sysAuxClkInt( ) - handle auxiliary clock interrupts
sysAuxClkRateGet( ) - get the auxiliary clock rate
sysAuxClkRateSet( ) - set the auxiliary clock rate
sysPhysMemTop( ) - get the address of the top of physical memory
The following routines are normally present only on targets that have a bus
interface:
sysProcNumGet( ) - get the processor number
sysProcNumSet( ) - set the processor number
sysBusIntAck( ) - acknowledge a bus interrupt
sysBusIntGen( ) - generate a bus interrupt
sysBusTas( ) - test and set a location across the bus
sysBusTasClear( ) - clear a location set by sysBusTas( )
sysBusToLocalAdrs( ) - convert a bus address to a local address
sysIntDisable( ) - disable a bus interrupt level
sysIntEnable( ) - enable a bus interrupt level
sysLocalToBusAdrs( ) - convert a local address to a bus address
