Programmer Mode
Mode Setting
at logic 0 and the BW1 and P40 pins at logic 1. In Programmer mode, the flash memory can be read,
erased and programmed using a general-purpose EPROM programmer. For instructions about the
settings of the remaining pins, see Section 3.7.3, Pin Functions and Settings. Figure 3.25 below shows
the pin settings for Programmer mode.
The TMP1940FDBF is placed in Programmer mode by holding the
