A22 I –
Non-Maskable Interrupt Input
(input pad with input spike-filter.)
HDRST A23 I/O A2
Hardware Reset Input / Reset Indication
Output
(open drain pad with input spike-filter.)
PORST B22 I –
Power-on Reset Input
(input pad with input spike-filter.)
BYPASS A24 I A1
PLL Bypass Select Input
This input has to be held stable between to
power-on resets. With BYPASS = 1 the
spike filters in the HDRST, PORST, and
NMI inputs are switched off.
TEST B23 I –
MODE
Test Mode Select Input
For normal operation of the TC1796, this
pin should be connected to high level.
(input pad, test function only, without input
spike-filter.)
TSTRES G24 I –
Test Reset Input
For normal operation of the TC1796, this
pin should be connected to low level.
Otherwise an unpredictable reset behavior
may occur.
(input pad, test function only, without input
spike-filter.)
