7. CHIP MODES
7.1 Types
There are four types of chip modes. Note that default pin assignments change depending upon
the chip mode.
Normal Mode
This mode is normally used.
External ROM Connection Mode
This mode is used for connection to external ROM.
External CPU Connection Mode
This mode is used for debugging. When this mode is activated, the internal microcontroller
does not operate.
Test Mode
This mode is used for testing. The test mode is not normally used.
7.2 Settings
Chip modes are determined by the status of pcfg[1:0] when the power-on-reset signal (porn
signal) rises.
pcfg [1 : 0] = 11
Normal Mode
pcfg [1 : 0] = 01
External CPU Connection Mode
pcfg [1 : 0] = 10
External ROM Connection Mode
pcfg [1 : 0] = 00
Test Mode
