10.4 Bootloader
This program (contained in an on-chip boot ROM) handles copying of
user code from an external EPROM into the on-chip EPROM. The
bootloader function does not have to be done from an external EPROM,
but can be done from a host.
10.4.1 Bootloader Functions
Two pins are used to select the bootloader function. These pins are PC1
and PB5. PC1 is normally a SYNC pin, which is used to synchronize the
MCU to an off-chip source that is driving EPROM data into the MCU. The
programmer/host interface is shown in Figure 10-1.
Figure 10-1. Programmer Interface to Host
If an external EPROM is used, this pin (PC1) must be connected to V
SS
.
PB5 is used to select between program/verify or verify-only modes. Two
other pins, PB2 and IRO, are used to drive the VERF LED and the
PROG LED respectively. The programming modes are shown in Table
The bootloader programming board shown in Figure 10-2 uses an
external 12-bit counter to address the memory device containing the
code to be copied. This counter requires a clock and a reset function.
The 12-bit counter can address up to 4 Kbytes of memory, which means
that two port pins have to be used to address the extra memory space.
