(1) The cumulative program time must not be exceeded when writing to a 128-byte flash block. This parameter applies to all programming
methods: individual word/byte write and block write modes.
(2) These values are hardwired into the flash controller's state machine.

(1) Tools accessing the Spy-Bi-Wire interface need to wait for the minimum t_SBW,En time after pulling the TEST/SBWTCK pin high before
applying the first SBWTCK clock edge.
(2) f_TCK may be restricted to meet the timing requirements of the module selected.
