CCS/TM4C1294NCPDT: CRC BASE macro definition incorrect in TivaWare manual

Bruno Saraiva
Guru 13040 points
Part Number: TM4C1294NCPDT

Tool/software: Code Composer Studio

An old and locked post had already pointed this out...

However, a few versions of Tivaware were published since then, and the manual remains incorrect, so it might be the case of "reminding" TI.

e2e.ti.com/.../360408

User guide "programming example", chapter 7.3, refers to the CRC base as EC_BASE, while the correct is CCM0_BASE.

Regards

    Hi Bruno,

     I just checked and you are correct and I apologize that the mistake remains.

    main(void)
{
//
// Enable the CRC module.
//
SysCtlPeripheralEnable(SYSCTL_PERIPH_CCM0);
//
// Wait for the CRC module to be ready.
//
while(!SysCtlPeripheralReady(SYSCTL_PERIPH_CCM0))
{
}
//
// Configure the CRC module.
//
CRCConfigSet(EC_BASE,
CRC_CFG_INIT_SEED |
CRC_CFG_TYPE_P4C11DB7 |
CRC_CFG_SIZE_32BIT);
//
// Set the seed value.
//
CRCSeedSet(EC_BASE, 0x5a5a5a5a);
//
// Process the data and get the result. The result should be
// 0x75fd6f5c.
//
g_ui32Result = CRCDataProcess(EC_BASE, g_ui32RandomData, 16, false);
}
