(1) The external signal sets the interrupt flag every time the minimum t_(int) parameters are met. It might be set with trigger signals shorter
than t_(int).
5.7 Leakage Current – Ports P1 to P6⁽¹⁾
over recommended operating free-air temperature range (unless otherwise noted)
I_lkg(Px.y)
PARAMETER
Leakage current, Port Px
V(Px.y) ⁽²⁾
TEST CONDITIONS
V_CC = 2.2 V, 3 V
(1) The leakage current is measured with V_SS or V_CC applied to the corresponding pins, unless otherwise noted.
(2) The port pin must be selected as input.
