MPU and MPUI Port
Table 92. MPUI Control Register (MPUI_CONTROL) (Continued)
Bit Name
3 API_ERR_EN
2 Reserved
1 TIMEOUT_EN
0 Reserved
Note: For 32-bit words, enabling byte swaps with BYTE_SWAP_CTL does the following: (1) performs a 16-bit word swap, (2)
within those 16-bit words, a byte swap occurs.
Table 93. Debug Address Register (DEBUG_ADDRESS)
Bit Name
31:24 Reserved
23:0 ADR_SAV
180 OMAP3.2 Subsystem
Base Address = 0xFFFE C900, Offset = 0x00
Function
Send MPUI port abort.
0: Mask the abort
1: An abort signal is forwarded by MPUI to the MPU for
an aborted MPUI port transaction.
API_ERR_EN only affects MPUI port aborts. It does
not enable/disable aborts to MPU/OCP-I/system DMA
for aborts generated directly by MPUI. For instance, a
timeout-generated abort in the MPUI is not affected by
API_ERR_EN setting.
Enable or disable TIMEOUT functionality as
characterized by register bits (15:8).
0: Do not enable TIMEOUT functionality.
1: Enable TIMEOUT functionality.
Base Address = 0xFFFE C900, Offset = 0x04
Function
Bits 23 down to 0 of address bus from MPU, OCP-I
or system DMA interface are saved when abort or
access size mismatch occurs.
