Status Register (Status_Reg) - Offset: X10 - Texas Instruments OMAP5910 Technical Reference Manual

Table 2–52. Debug Flag Register (DEBUG_FLAG) – Offset: x0C (Continued)
Bit Value Function
3 Flag set to 1 when burst size saved on abort is not
equal to 000
2 Flag set to 1 when MPUIF access is aborted by internal
time out
1 Flag set to 1 when MPUI aborts access
0 Flag set to 1 when MPUI port on DSP subsystem
aborts the access
Table 2–53. Status Register (STATUS_REG) – Offset: x10
Bit Value Function
12–11 Current access in progress is:
00 MPU access
01 DMA access
10 Reserved port access, should not occur
11 No access
10–3 Current value of time-out counter
2 Enable chip-select bit indicates when MPU wait states
are being inserted, which forces chip-selects to inac-
tive:
0 CSs are forced to inactive state (high).
1 CSs are enabled and can be asserted.
1 0 MPUIF is accessing MPUI.
1 No access in progress
The STATUS_REG checks the status of the MPU interface during suspend
mode (for example, after hitting an emulator breakpoint). The register is for
OMAP5910 device chip designers to use for debugging.
