ATE Flash Program Access
9.6.1
Overview
The ATE Flash Program Access function enables the 64k Embedded Flash to be programmed from an
external parallel hardware interface using the KBD Scan interface in the LPC47N350 pin configuration.
The Flash Program Interface Decoder enables the ATE Flash Program Access function (Table 9.1, item
#4) (see Section 9.6.3, "PGM Pin").
A block diagram of the ATE Flash Program Access Interface is shown below in Figure 9.3. The ATE
Flash Program Access pin mapping to the KBD Scan interface pins is shown in Table 9.2. For
information regarding the programming sequence for the LPC47N350 64k Embedded Flash see Section
8.3, "Command Sequence Interface (CSI)".
