Function
System bus data burst size indicated from MPU core
on abort. Can be used in conjunction with
BURST_SIZE_ERR flag bit.
Valid OMAP 3.2 burst size values:
000: One data burst (single-access)
011: Four-data burst
Since MPUI port supports single-access only, a 000
value is expected; otherwise, an abort is generated.
Indicates read or write transaction on the MPUI upon
abort.
0: Write transaction
1: Read transaction
Data width of the MPUI port access upon abort. Note
that the MPUI handles 32-bit accesses from
MPU/OCP-I/system DMA as successive 16-bit
transactions to fit the 16-bit interface of the MPUI port.
0: 8-bit access
1: 16-bit access
Flag set to 1 when the system bus data burst size
indicated from the MPU core is not 000. Because
MPUI port supports single-access only, a 000 value is
always expected. The value of the burst indicated by
MPU core is saved in bits (8:6).
When read, this bit is reset to 0.
Flag set to 1 when MPUI access is aborted by internal
timeout.
When read, this bit is reset to 0.
Flag set to 1 when MPUI port aborts access.
When read, this bit is reset to 0.
Flag set to 1 when MPUI access is aborted.
When read, this bit is reset to 0.
