2.6 Pin Functions in Reset and Power Save Modes
The following table summarizes the status of the pins during reset and power
save modes and after release of these operating states in normal operation
mode, i.e. FLMD0 = 0.
The reset source makes a difference concerning the N-Wire debugger
interface pins DRST, DDI, DDO, DCK and DMS after reset release. An external
RESET or an internal Power-on-clear switches all pins to input port mode,
while all other internal reset sources make the pins available for the debugger.
In contrast to all other power save modes the HALT mode suspends only the
CPU operation and has no effect on any pin status.
Pin functions and reset / power save modes
a)
If flash programming mode is enabled by FLMD0 = 1 P07 is used as FLMD1
pin in input port mode during and after reset.
