ID[1:0] (Identification). The device whose ID input pins/balls match the value of bits ID[0:1]
responds to read and write cycles to register space.
Reserved for future use.
VCCQ_3V: Reflects the level of VCCQ input.
0: VCCQ < 2.0V
1: VCCQ > 2.5V
Reserved for future use.
MAX_ID (Maximum Device ID). This field controls the Programmable Boot Block address
mapping when multiple devices are used in a cascaded configuration, using the ID[1:0]
inputs. It should be programmed to the highest ID value that is found by software in order to
map all available boot blocks into usable address spaces.
IF_CFG (Interface Configuration). Reflects the state of the IF_CFG input pin.
In a cascaded configuration, this register controls which device provides the
register space. The value of bits ID[0:1] is compared to the value of the ID
configuration input pins/balls. The device whose ID input matches the value of
bits ID[0:1] responds to read and write cycles.
This register indicates the current configuration of DiskOnChip G4. Unless
otherwise noted, the bits are reset only by a hardware reset, and not upon boot
detection or any other entry to Reset mode.
