21.5.21 Fabric Interface Control (FIC) Register

Table 21-27. FAB_IF_CR
Bit Number Name Reset Value Description
[31:10] Reserved 0
[9:4] SW_FIC_REG_SEL 0x38 Indicates whether a specific fabric region is accessible by FIC_0 or FIC_1. This register should not be changed during operation.

0: Fabric region associated with FIC_0

1: Fabric region associated with FIC_1

By default, fabric region 0, 1, 2 are accessible through FIC_0 and regions 3, 4, 5 are accessible through FIC_1.

These bits are driven into the AHB bus in order to allocate a specific memory region to either FIC_0 or FIC_1.

3 FAB1_AHB_MODE 0 Controls whether the FIC_1 fabric interface supports AHB mode or APB mode. Allowed values:

0: Supports APB mode

1: Supports AHB mode

2 FAB0_AHB_MODE 0 Controls whether FIC_0 fabric interface supports AHB mode or APB mode. Allowed values:

0: Supports APB mode

1: Supports AHB mode

1 FAB1_AHB_BYPASS 0 0: FIC_1 is configured for synchronous bridging

1: FIC_1 is configured in bypass mode, if clock ratio is 1:1 and if in AHB mode

0 FAB0_AHB_BYPASS 0 0: FIC_0 is configured for synchronous bridging

1: FIC_0 is configured in bypass mode, if clock ratio is 1:1 and if in AHB mode

Note: Do not change these register fields dynamically for 005 and 010 devices, see 21.5.1 System Registers Behavior for M2S005/010 Devices.
