Chapter 30 Intelligent Peripheral (SPI Slave) Functions vAHI_IpRegisterCallback (JN5148/JN5139 Only) void vAHI_IpRegisterCallback( PR_HWINT_APPCALLBACK prIpCallback); Description This function registers an application callback that will be called when the SPI interrupt is triggered. The interrupt is generated when either a transmit or receive transaction has completed. The registered callback function is only preserved during sleep modes in which RAM remains powered. If RAM is powered off during sleep and interrupts are required, the callback function must be re-registered before calling u32AHI_Init() on waking. Interrupt handling is described in Appendix A. Parameters prIpCallback Pointer to callback function to be registered Returns None 366 © NXP Laboratories UK 2011 JN-UG-3066 v3.0
