USER’S MANUAL
RESET:
15
When LAT is cleared, the TPUFLASH address and data buses are connected to the
IMB address and data buses. The TPUFLASH is configured for normal reads. When
LAT is set, the TPUFLASH address and data buses are connected to parallel internal
latches. The TPUFLASH array is configured for programming or erasing.
Once LAT is set, the next write to a valid TPUFLASH address causes the program-
ming circuitry to latch both address and data. Unless control register shadow bits are
to be programmed, the write must be to an array address.
The value of LAT cannot be changed when program/erase voltage is turned on (ENPE
= 1).
ENPE can be set only after LAT has been set, and a write to the data and address
latches has occurred. ENPE remains cleared if these conditions are not met. While
ENPE is set, the LAT, VFPE, and ERAS bits cannot be changed, and attempts to read
a TPUFLASH array location are ignored.
TFBS[3:0] can be used as system bootstrap vectors. When BOOT = 0 in TFMCR dur-
ing reset, the TPUFLASH responds to program space accesses of IMB addresses
$000000 to $000006 after reset. When BOOT = 1, the TPUFLASH responds only to
normal array and register accesses. TFBS[3:0] can be read at any time, but the values
in the words can only be changed by programming the appropriate locations.
0 = Disable program/erase voltage.
1 = Apply program/erase voltage.
