9.3 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.

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.
A write to this register selects the current logical
