Table 2-58. RAM Control Register (RAMGCR) Field Descriptions
Bit Field Value Description
31-20 Reserved 0 Reads return 0. Writes have no effect.
19-16 RAM_DFT_EN Functional mode RAM DFT (Design For Test) port enable key.
Note: For TI internal use only.
Ah RAM DFT port is enabled.
Others RAM DFT port is disabled.
Note: It is recommended that a value of 5h be used to disable the RAM DFT port. This value
will give maximum protection from a bit-flip inducing event that would inadvertently enable
the controller.
15 Reserved 0 Reads return 0. Writes have no effect.
14 Reserved 0-1 Reads return 0 or 1 depends on what is written in privileged mode. The functionality of this bit is
unavailable in this device.
13 Reserved 0 Reads return 0. Writes have no effect.
12 Reserved 0-1 Reads return 0 or 1 depends on what is written in privileged mode. The functionality of this bit is
unavailable in this device.
11 Reserved 0 Reads return 0. Writes have no effect.
10 Reserved 0-1 Reads return 0 or 1 depends on what is written in privileged mode. The functionality of this bit is
unavailable in this device.
9 Reserved 0 Reads return 0. Writes have no effect.
8 Reserved 0-1 Reads return 0 or 1 depends on what is written in privileged mode. The functionality of this bit is
unavailable in this device.
