AM4372: memory-mapped port of QSPI

Hi Melissa-san,

Thank you for your support.

I understood QSPI_SPI_CMD_REG register are only applicable to configuration port mode.

Please tell me more about the following.

In memory-mapped mode, the effective WLEN and FLEN values are handled by an internal state machine.

What is the value of WLEN and FLEN for each of (A) and (B) below?

(A)
uint8_t *pSrc; /* Source address */
uint8_t *pDst; /* Destination address */

count = 3;

while(count)
{
    *pDst = *pSrc;
    pDst++;
    pSrc++;
    count--;
}


(B)
uint32_t *pSrc; /* Source address */
uint32_t *pDst; /* Destination address */

count = 3;

while(count)
{
    *pDst = *pSrc;
    pDst++;
    pSrc++;
}

I'd like to know where the frame ends.

Best regards,
