4.2 Attaching the Adapter to a PROM Programmer As shown in Figure 4.1, attach the pin No. 1 of the PCA7402D PROM programmer connector (Standard-pitch 28-pin pin-header mounted) to the pin No. 1 of the IC socket of the PROM programmer. Be careful when attaching the adapter because incorrect insertion can cause fatal damage to the MCU. Figure 4.1 Attaching the adapter to a PROM programmer 4.3 Inserting an MCU into Programming Adapter (1) As shown in Figure 4.2, set the slide bar of the IC socket t
