This section identifies the requirements of initializing the interfacing modules when the TRNG is to be used for the first time after a device reset. Table 14-2 lists the Initialization of interfacing modules.
Interfacing Module | Comment |
---|---|
PRCM | TRNG module interface clock must be enabled. See PRCM:PDCTL0.PERIPH_ON and PRCM:SECDMACLKGR.TRNG_CLK_EN in Section 7.8.1 |
Arm® Cortex®-M33 | NVIC configuration must be done to enable the interrupt from the TRNG. Only needed for interrupt based communication. |
Interconnect | Interconnect must be enabled for communication with TRNG, which is handled in the PRCM as a consequence of many settings like CPU in run, sleep, or deep sleep mode, usage of DMA, I2S, RFCORE, and Crypto engine. |
