Figure 6-1. MC68HC(7)05CJ4 Mode Entry Diagram
6.3 Single-Chip Mode (SCM)
In this mode, all address and data bus activity occurs within the MCU so no
external pins are required for these functions. The single-chip mode allows the
maximum number of I/O pins for on-chip peripheral functions, port A through
port D.
6.4 Self-Check/Bootstrap Mode
In this mode, the reset vector is fetched from a 240-byte internal self-check
(bootstrap for MC68HC705CJ4) ROM at $1F00:$1FEF. The self-check ROM
contains a self-check program to test the functions of internal modules. The
bootstrap ROM contains a small program which reads a program into the internal
RAM and then passes control to that program at location $0020, or executes
EPROM programming sequence and dumps EPROM contents.
Since these modes are not normal user modes, all of the privileged control bits are
accessible. This allows the self-check/bootstrap mode to be used for self testing
the device.
6.5 Low-Power Modes
The following sub-sections describe the low-power modes. Figure 6-2 provides a
timing diagram of the stop recovery mode and Figure 6-3 a flowchart for the stop
and wait modes.
