type of AHBPrescTable[] and APBPrescTable[]

[CanastraRF]

Hi

Why is the type of AHBPrescTable[] and APBPrescTable[] uint32_t?

const uint32_t AHBPrescTable[16U] = {0UL, 0UL, 0UL, 0UL, 0UL, 0UL, 0UL, 0UL, 1UL, 2UL, 3UL, 4UL, 6UL, 7UL, 8UL, 9UL};
const uint32_t APBPrescTable[8U] = {0UL, 0UL, 0UL, 0UL, 1UL, 2UL, 3UL, 4UL};

All other families has got uint8_t

const uint8_t AHBPrescTable[16U] = {0U, 0U, 0U, 0U, 0U, 0U, 0U, 0U, 1U, 2U, 3U, 4U, 6U, 7U, 8U, 9U};
const uint8_t APBPrescTable[8U] = {0U, 0U, 0U, 0U, 1U, 2U, 3U, 4U};

can you explain?
