Connecting the Emulator Port Pins
Capacitors to ground must be used for protection from EMI. Production boards should have the ICE_E pin connected to
ground.
If the ICE pins are used to drive LCD segments, the pull-up resistors should be omitted, as shown in Figure 37, and 22pF
capacitors to GNDD should be used for protection from EMI.
It is important to bring out the ICE_E pin to the programming interface in order to create a way for reprogramming
parts that have the flash SECURE bit (SFR 0xB2[6]) set. Providing access to ICE_E ensures that the part can be reset
between erase and program cycles, which will enable programming devices to reprogram the part. The reset required is im-
plemented with a watchdog timer reset (i.e. the hardware WDT must be enabled).
