INDEX
Note:
Note 1: CR22 bit 5 and bit 7 are reset on VTR only.
Note 2. Bits[6:5] reset on VTR POR only.
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.
