On Chip Debug Support – OCDS
There is an EV chip named HT67V5630 which is used to emulate the HT67F5630 device. The EV
chip device also provides an “On-Chip Debug” function to debug the real MCU device during the
development process. The EV chip and the real MCU device are almost functionally compatible
except for “On-Chip Debug” function. Users can use the EV chip device to emulate the real chip
device behavior by connecting the OCDSDA and OCDSCK pins to the Holtek HT-IDE development
tools. The OCDSDA pin is the OCDS Data/Address input/output pin while the OCDSCK pin is
the OCDS clock input pin. When users use the EV chip for debugging, other functions which are
shared with the OCDSDA and OCDSCK pins in the device will have no effect in the EV chip.
However, the two OCDS pins which are pin-shared with the ICP programming pins are still used
as the Flash Memory programming pins for ICP. For more detailed OCDS information, refer to the
corresponding document named “Holtek e-Link for 8-bit MCU OCDS User’s Guide”.
