Chip Level (Global) Control/Configuration Registers [0x00-0x2F]
The chip-level (global) registers lie in the address range [0x00-0x2F]. The design MUST use all 8 bits of
the ADDRESS Port for register selection. All unimplemented registers and bits ignore writes and return
zero when read.
The INDEX PORT is used to select a configuration register in the chip. The DATA PORT is then used to
access the selected register. These registers are accessible only in the Configuration Mode.

TABLE 63 - CHIP LEVEL REGISTERS
Reserved - Writes are ignored, reads return 0.
The hardware automatically clears this bit after the write,
there is no need for software to clear the bits.
Bit 0 = 1: Soft Reset. Refer to the "Configuration Registers"
table for the soft reset value for each register.

Reserved - Writes are ignored, reads return 0.
A write to this register selects the current logical device.
This allows access to the control and configuration registers
for each logical device.
operates only on the selected logical device.
Reserved - Writes are ignored, reads return 0.
