9-2-7. LVR

(1) VDD must reach or above 2.2V for successful power-on process; otherwise IC will be inactive.

(2) The setting of LVR (1.8V, 2.0V, 2.2V etc) will be valid just after successful power-on process.

9-2-8. IHRC

(1) The IHRC frequency calibration is performed when IC is programmed by the writer.

(2) Because the characteristic of the Epoxy Molding Compound (EMC) would some degrees affects the IHRC

frequency (either for package or COB), if the calibration is done before molding process, the actual IHRC

frequency after molding may be deviated or becomes out of spec. Normally , the frequency is getting

slower a bit.

(3) It usually happens in COB package or Quick Turnover Programming (QTP). And PADAUK would not take

any responsibility for this situation.

(4) Users can make some compensatory adjustments according to their own experiences. For example, users

can set IHRC frequency to be 0.5% ~ 1% higher and aim to get better re-targeting after molding.

9-2-9. Program writing

There are 8 pins for using the writer to program: PA0，PA3， PA4， PA5， PA6， PA7， VDD, and GND.

User can program PMC232/PMS232 from using PDK3S-P-002:

(1) Put the PMC232/PMS232-S14/D14 in the top of the textool over the CN36.

(2) Put the PMC232/PMS232-S20/D20 in the top of the textool over the CN37.

(3) Put the PMC232/PMS232-S18/D18 to move down one space over CN37.

(4) Other packages could be programmed by user’s way.

All the left signs behind the jumper are the same (there are VDD, PA0, PA3, PA4, PA5, PA6, PA7, and

GND).The following picture is shown:

If user use PDK5S-P-003 or above to program, please follow the instruction.
