driven low prior to the end of Power-On Reset (POR). After POR has completed the device
will remain in ISP mode until RST is brought high. Once the initial ISP session has ended, the
power to the target device must be cycled OFF and ON to enter another session.
The SS pin should not be left floating during reset if ISP is enabled.
The ISP Enable Fuse must be set to allow programming during any reset period. If the ISP
Fuse is disabled, ISP may only be entered at POR.

Memory Organization
The AT89LP213/214 offers 2K bytes of In-System Programmable (ISP) nonvolatile Flash code
memory. In addition, the device contains a 64-byte User Signature Array and a 32-byte read-
only Atmel Signature Array. The memory organization is shown in Table 23-1 and Figure 23-2.
The memory is divided into pages of 32 bytes each. A single read or write command may only
access a single page in the memory. Each memory type resides in its own address space and is
accessed by commands specific to that memory. However, all memory types share the same
page size.
User configuration fuses are mapped as a row in the memory, with each byte representing one
fuse. From a programming standpoint, fuses are treated the same as normal code bytes except
they are not affected by Chip Erase. Fuses can be enabled at any time by writing 00h to the
appropriate locations in the fuse row. However, to disable a fuse, i.e. set it to FFh, the entire
fuse row must be erased and then reprogrammed. The programmer should read the state of all
the fuses into a temporary location, modify those fuses which need to be disabled, then issue a
Fuse Write with Auto-Erase command using the temporary data. Lock bits are treated in a simi-
lar manner to fuses except they may only be erased (unlocked) by Chip Erase.
