SECTION 6
OPERATING MODES
The HC05BD7/HC05BD2 has the following operating modes: single-chip mode (SCM) and
self-check mode.
The HC705BD7 has the following operating modes: User mode and bootstrap mode.
6.1
User Mode
In this mode, all address and data bus activity occurs within the MCU so no external pins
are required for these functions.
6.2
SELF-CHECK MODE
In this mode, the reset vector is fetched from the 240-byte internal self-check ROM at
$3F00:$3FEF. The self-check ROM contains a self-check program to test the functions of
internal modules.
6.3
Bootstrap Mode
In this mode, the reset vector is fetched from the 480-byte internal bootstrap ROM at
$0E00:$0FDF. The bootstrap ROM contains a small program which reads a program into
internal RAM and then passes control to execute EPROM programming.
6.4
Mode Entry
The mode entry is done at the rising edge of the RESET pin. Once the device enters one
of the operating modes, the mode can only be changed by an external reset.
At the rising edge of the RESET pin, the device latches the states of IRQ and PB5 pins and
places itself in the specified mode. While the RESET pin is low, all pins are configured as
Single Chip Mode. The following table shows the states of IRQ and PB5 pins for each mode
entry.
