Flash Memory
NOTES: 1. The cumulative program time must not be exceeded when writing to a 64-byte flash block. This parameter applies to all programming
RAM
NOTE 1: This parameter defines the minimum supply voltage V CC when the data in RAM remains unchanged. No program execution should
JTAG Interface
NOTES: 1. f TCK may be restricted to meet the timing requirements of the module selected.
JTAG Fuse (see Note 1)
NOTES: 1. Once the fuse is blown, no further access to the JTAG/Test and emulation feature is possible and is switched to bypass mode.
