General Release Specification
MC68HC705C9A — Rev. 2.0
A.3 Bootloader Mode
Bootloader mode is entered upon the rising edge of RESET if the IRQ is
at VTST and the TCAP pin is at logic one. The bootloader code resides
in the ROM from $3F00 to $3FEF. This program handles copying of user
code from an external EPROM into the on-chip EPROM. The bootload
function does not have to be done from an external EPROM, but it may
be done from a host.
The user code must be a one-to-one correspondence with the internal
EPROM addresses.
A.4 Bootloader Functions
Three pins are used to select various bootloader functions: PD5, PD4,
and PD3. Two other pins, PC6 and PC7, are used to drive the PROG
LED and the VERF LED, respectively. The programming modes are
shown in Table A-2.
