f_(TAext)
Timer_A clock frequency externally
applied to pin

NOTES: 1. The external signal sets the interrupt flag every time the minimum t_(int) parameters are met. It may be set even with trigger signals
shorter than t_(int).
leakage current -- Ports P1, P2, P3, P4, P5, and P6 (see Note 1)
PARAMETER
TEST CONDITIONS
MIN MAX
I_lkg(Px.y)
Leakage current
Port Px V_(Px.y) (see Note 2)
V_CC = 2.2 V/3 V
±50
NOTES: 1. The leakage current is measured with V_SS or V_CC applied to the corresponding pin(s), unless otherwise noted.
2. The port pin must be selected as input.
