Synchronous Serial Interface (SSI)
Prototype:
uint32_t
ROM_SSIIntStatus(uint32_t ui32Base,
bool bMasked)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_SSITABLE is an array of pointers located at ROM_APITABLE[2].
ROM_SSIIntStatus is a function pointer located at ROM_SSITABLE[6].
Parameters:
ui32Base specifies the SSI module base address.
bMasked is false if the raw interrupt status is required or true if the masked interrupt status is
required.
Description:
This function returns the interrupt status for the SSI module. Either the raw interrupt status or
the status of interrupts that are allowed to reflect to the processor can be returned.
Returns:
The current interrupt status, enumerated as a bit field of SSI_TXFF, SSI_RXFF, SSI_RXTO,
and SSI_RXOR.

Prototype:
void
ROM_UpdateSSI(void)
ROM Location:
ROM_APITABLE is an array of pointers located at 0x0100.0010.
ROM_SSITABLE is an array of pointers located at ROM_APITABLE[2].
ROM_UpdateSSI is a function pointer located at ROM_SSITABLE[11].
Description:
Calling this function commences an update of the firmware via the SSI0 interface. This function
assumes that the SSI0 interface has already been configured and is currently oprational.
Returns:
Never returns.
