Reserved, set to 0.
When set to 1, the internal IMA/TC UTOPIA interface is disabled.
Reserved, set to zero.
Controls the ATM-side UTOPIA interface mux.
When set to 0, the 16-bit UTOPIA bus is enabled. When set to 1, the 8-bit UTOPIA
bus is enabled. When the ATM UTOPIA interface to IMA32 block is enabled
(ATMmux[1:0] = "01"), this bit controls the bus width of the IMA32 core ATM-side
UTOPIA interface. In this case, the TC ATM-side UTOPIA interface is always 8-bit.
When the ATM UTOPIA interface to TC block is enabled, (ATMmux[1:0] = "10"),
this bit controls the bus width of the TC ATM-side UTOPIA interface.
Reserved, set to zero.
Reserved, set to zero.
Reserved, set to zero.
Reserved, set to zero.
The value written into these bits will be asserted on the StatOut[1:0] output pins.
00 – External interface is placed in Tristate mode.
01 – Utopia level 2 interface to IMA32 block is enabled.
10 – Utopia level 2 interface to TC block is enabled.
11 – External interface is placed in Tristate mode.
