lowest numbered block and will also be located in small block 0 if the lowest numbered block hosts a small

21.3.7.3
The program operation may be suspended to allow read accesses to the array. Setting the HSUS bit in the
UC3FCTL to a 1 while PE = 0, EHV = 1, and HVS = 1 forces the array into a program suspend state. The
deassertion of the HVS bit (HVS = 0) signifies that the program operation has been successfully
suspended. The HVS bit should negate within 10µs of asserting the HSUS bit.
While in program suspend mode, normal read accesses may be performed to the UC3F array or shadow
information words. Reads to the array location targeted for program return indeterminate data since only
a partial programming operation may have been performed.
The program operation may be resumed by setting HSUS = 0.
21.3.8
To modify the charge stored in an isolated element of the UC3F bit from a logic 0 state to a logic 1 state,
an erase operation is required. In the UC3F EEPROM, erase is a bulk operatBlockion that affects the stored
charge of all the isolated elements in an array block. To make the UC3F module block-erasable, the array
is divided into blocks that are physically isolated from each other. Each of the array blocks may be erased
in isolation or in any combination. The UC3F array block size is fixed for all blocks in the module at 64
Kbytes and the module is comprised of eight blocks. Two of these blocks may be further subdivided into
two small blocks. Array blocks of the UC3F EEPROM that are protected (PROTECT[M] = 1 or
(SBEN[M] = 1 & SBPROTECT[M] = 1)) will not be erased. Also, if EPEE = 0 or B0EPEE = 0, no erase
voltages will be applied to the array or the block corresponding to block 0 or small block 0 if SBEN[0] = 1.
The embedded program/erase algorithm first pre-programs all bits in blocks selected for erase prior to
actually erasing the selected blocks.
The array blocks selected for erase operation are determined by BLOCK[0:7], SBBLOCK[0:1] in
conjunction with SBEN[0:1], and the array configuration. If multiple blocks are selected for erase, the
embedded erase hardware algorithm serially erases each array block until all of the selected blocks are
erased. For instance, if BLOCK[0:7] = 0x78 and SBEN[0:1] = 0b00, then blocks 1, 2, 3, and 4 are selected
for erase. The embedded erase hardware algorithm first erases block 1 and then erases block 2 followed

Erasing
Program Suspend
Repeated suspending of a program operation to fetch array contents may
extend the program operation. The internal program hardware may only
resume the program operation at predefined steps of the internal program
hardware sequence; interrupting the program operation on a high frequency
basis may cause the internal program hardware to delay completion of the
current step and delay advancement to the next step of the internal program
hardware sequence. Frequent suspend/resume operations (more than
approximately once per millisecond) may also cause program or erase
timeouts, and are not recommended.
