362 / 401 page ![]() STR720 - MISCELLANEA REGISTERS (GCR - CGC - AHB_ERR) 362/401 AHB Error Faulty Address (AERR_FA) Address: 0xF000_3008 Reset value: 0x0000_0000 This register stores the address of the location whose access caused the AHB error response to be generated. When an AHB error is detected, the address of the faulty location is saved into this register and the AE_P bit in AERR_P register is set, causing a FIQ interrupt request to be issued if AE_M bit in AERR_M register is set as well. As long as the AE_P bit is not clear by application software, this register will keep the stored address even if further AHB error response occur. This is a read-only register. Bits 31:0 = AERR_FA: AHB Error Faulty Address 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 AERR_FA[31:0] r 15 14 13 12 11 10 9 8 765432 1 0 AERR_FA[31:0] r |
