Data Fields

uint16_t raw_esr
 Raw SRAMESR value.
uint8_t one_bit_mask
 Bit i = SRAMi 1-bit error.
uint8_t two_bit_mask
 Bit i = SRAMi 2-bit error.
uintptr_t addr_1bit [k_ra8_sram_bank_count]
 Captured 1-bit error address per bank.
uintptr_t addr_2bit [k_ra8_sram_bank_count]
 Captured 2-bit error address per bank.

Detailed Description

Snapshot of ECC error state (filled by ra8_sram_get_status).

Bits in raw_esr follow the SRAMESR layout exactly (HUM Ch 58.2.12 p 3535) – see ra8_sram_esr_bit_t in ra8_sram_regs.h. The decoded helpers one_bit_mask / two_bit_mask collapse those 8 bits into a per-bank bitmap (bit i = bank i).

addr_1bit[bank] / addr_2bit[bank] carry the absolute faulting address (EAR offset + 0x2200_0000), or 0 if no error has fired for that bank/slot.
