Standby
If pin NEN, featuring an internal pull-up, is not forced
low by an external signal, iC-MA3 remains in standby
mode. During this mode the tri-level mode control in-
puts M0, M1, PSEL, ASEL, FSEL, and the signal ports
P0 to P3 are all high impedance, so that a minimal
current consumption is obtained.

Test Mode
With pin NTM, iC-MA3 can be set to test mode for
iC-Haus device testing. If there is no external signal
forcing pin NTM low, the pin’s internal pull-up disables
the test mode. However, for safety pin NTM should be
connected to VDD to avoid any unwanted function.
