This section describes system limitations of the RKICS.
The RKICS communicates using the MON08 features. This forces the
communication rate to f
standard baud rates allowed by the host software. See 2.3.2.2 MCU Bus
Frequency Selection Header (W2) for available options.
Port A0 is used for communications, so it is unavailable for emulation.
The RF features of an MC68HC908RFRK2 installed in the QFP socket are not
available. For RF emulation, use the optional flex cable (order number
M68CLB05A) and QFP target head adapter (order number
M68TA08RK2FA32).
The LVI is disabled by default in monitor mode. It is enabled by a dummy write
to LVISR.
The ICG is bypassed in monitor mode, so it is not available for use.
Five jumper headers on the RKICS are used to reconfigure the hardware
options. Table 2-1 is a quick reference to these optional settings, while
subsections 2.3.2.1 through 2.3.2.4 describe jumper header configuration in
greater detail.
