RESET_b
RESET IN – Active-low input line to the OnCE controller, signalling a reset.
10
TMS
TEST MODE SELECT – Input signal that tells the OnCE control block to
advance one mode state (of the cycle of mode states).
11
VDD3V
+3.3-volt power.
12
DBEV_b
DEBUG EVENT – Active-low debug-mode control line for the OnCE controller.
An input signal from an external command controller makes the OnCE
controller immediately enter debug mode. An output signal acknowledges
debug-mode-entry to the external command controller.
14
TRST_b
TEST RESET – Active-low input line for an external reset signal to the OnCE
controller.
