This register is used for factory test only.
TFBAH contains the 16 high-order bits of the array base address; TFBAL contains the
active low-order bits of the array base address. During reset, both TFBAH and TFBAL
take on default values programmed into associated shadow registers. After reset, if
LOCK = 0 and STOP = 1, software can write to TFBAH and TFBAL to relocate the
TPUFLASH array. Because the states of ADDR[23:20] follow the state of ADDR19,
addresses in the range $080000 to $F7FFFF cannot be accessed by the CPU16. If
the TPUFLASH array is mapped to these addresses, the system must be reset before
the array can be accessed.
TFBAL is used to determine the base address and depends on the array size. The
shadow bits for TFBAL[15:11] are programmable, although some of the bits can be ig-
nored, depending on the array size. In this TPU flash, bit 11 will be ignored. Bits [15:12]
are used to map the 4-Kbyte TPUFLASH array to a 4-Kbyte address space.
TFCTL controls programming and erasure of the TPUFLASH.
