Data port for tag testing, bits 0-7.
next). Typical setting = 00h for normal operation (value has no effect). When tag test mode is
enabled, writes to the test window cause the value in this register to be written to bits 0-7 in the TAG
RAM. Reads from the test window cause TAG bits 0-7 to be written into this register.
Data port for tag testing, bits 8-10.
next). Typical setting = 00h for normal operation (value has no effect). See index 23h description.
Register bits 0-2 are tag bits 8-10. Register bits 3-7 are reserved.
