1. Outline
(2/4)
The M38C29T-64LCA is a converter board which connects the
100-pin RFS type emulator MCU (M38C13RLFS,
M38C29RLFS, M38K09RFS, M38K29RFS) to a foot pattern
for 64-pin 0.8-mm-pitch QFP (PRQP0064GA-A) and 64-pin
0.8-mm-pitch LQFP (PLQP0064GA-A).

4. Usage
4.1 Oscillator Circuit
The M38C29T-64LCA has two kinds of oscillator circuit
patterns for the main clock XIN and the sub clock XCIN.
Depending on the configuration of an oscillator circuit on the
user system use them as follows.
(1) To use the internal oscillator circuit of the MCU
Because the converter board exists between the emulator
MCU and the user system, the oscillator on the user system
may not be able to oscillate. In this case, mount an
oscillator circuit on an oscillator circuit pattern (see
Figures 2 and 3) of the M38C29T-64LCA. And, to confirm
its oscillation, check output waveforms of pins XOUT and
XCOUT using an oscilloscope.
(2) To use an oscillator module IC
You do not need to mount an oscillator circuit on oscillator
circuit pattern of the M38C29T-64LCA.
