Note: The Emulation Mode, known from other C16x Infineon devices, is not supported
Adapt Mode
Table 91
Pin P0L.1 (ADP) selects the Adapt Mode when low during reset. It is latched with the
rising edge of RSTIN. In this mode the C161U goes into a passive state, which is similar
to its state during reset. The pins of the C161U float to tristate or are deactivated via
internal pullup/pulldown devices, as described for the reset state. In addition also the
RSTOUT pin floats to tristate rather than be driven low, and the on-chip oscillator is
switched off.
This mode allows switching a C161U that is mounted to a board virtually off, so an
emulator may control the board’s circuitry, even though the original C161U remains in its
place. The original C161U also may resume to control the board after a reset sequence
with P0L.1 high.
Default: Adapt Mode is off.
Bootstrap Loader Mode
Pin P0L.4 (BSL) activates the on-chip bootstrap loader, when low during reset. The
bootstrap loader allows moving the start code into the internal RAM of the C161U via the
serial interface ASC. The C161U will remain in bootstrap loader mode until a hardware
reset with P0L.4 high or a software reset.
Default: The C161U starts fetching code from location 00’0000
off.
External Bus Type
Pins P0L.7 and P0L.6 (BUSTYP) select the external bus type during reset, if an external
start is selected via pin EA. This allows the configuration of the external bus interface of

by the C161U. Make sure, on pin P0L.0 a HIGH signal is always latched in. HIGH
on P0L.0 is the default configuration and is supported by the internal pull-up
device.
