Could you tell me all AxPROT values that can be generated on ARM1176 ?

Applies to: ARM1176

Answer

The following values are possible.

AxPROT[2:0] signal = x, y, z where x, y, z can take any value

ARPROTI = 1(instruction), y(security S/NS), z(user/privileged mode)

ARPROTRW = 0(data), y(security S/NS), z(user/privileged mode)

AWPROTRW = 0(data), y(security S/NS), z(user/privileged mode)

ARPROTD = x(data TCM/instruction TCM), y(security S/NS), z(user/privileged mode)

AWPROTD = x(data TCM/instruction TCM), y(security S/NS), z(user/privileged mode)

ARPROTP = 0(data), y(security S/NS), z(user/privileged mode)

AWPROTP = 0(data), y(security S/NS), z(user/privileged mode)
