Using the MON08 Interface
MOTOROLA
Using the MON08 Interface
4.3 Target Requirements for Using MON08
The MRICS connects PTB1..3 to TGT-PTB1..3, except during reset. During
reset, PTB1..3 have voltages placed on them that configure the processor to
enter the proper mode when coming out of reset.(The preceding is true for the
MR16/32 but not the MR4/8) Refer to Section 9, Monitor ROM, in the Motorola
MC68HC908MR manual for more information. PTB0 will not be connected to
TGT-PTB0 because this signal is used for serial communications with the
debugging software.(This sentence should refer to PTA0 and TGT_PTA0 for
the MR16/32. For the MR4/8 it should be PTB0 and PTB1 not connected to
TGT_MR4_PTB0 and TGTMR4_PTB1)
Any pullups on the reset and IRQ signals should be on the target board side of
the MON08 connector and not on the MCU side. Any connections to RST or
IRQ may cause MON08 debugging to fail and may damage components on the
target since these signals will go up to 8.6 Vdc.
4.4 Connecting to the In-Circuit Simulator
Using the 16-pin cable provided with the MRICS kit, connect one end of the
cable to the MRICS board at J7 (for the MR16/32) or J8 (for the MR4/8).
Connect the other end to connector P1 on the target-system board. The pin-1
indicators on each cable end must correspond to the pin-1 indicators on the
headers. P2 is not used when connecting to the MRICS board.
