  • RE: TM4C1237H6PM: Lock-Up at power brown out event

    Steven Li said: One thing we found that, from the locked MC, the signal at ICDI_TDO port (pin 49) goes to low for about 77ms then goes high for the next 77ms -- like a 13Hz clock signal. Section 5.2.2.1 Reset Sources of the TM4C1237H6PM datasheet contains…
