7-modes
EPROM containing the user code are incremented independently it is
essential that the data layout in the 2764 EPROM conforms exactly to
the MC68HC705X4memory map.
The bootloader uses an external 12-bit counter with a clock and a reset
function to address the memory device containing the code to be copied.
The 12-bit counter can address up to 4K bytes of memory therefore a
port pin must be used to address the additional memory space.
NOTE:
In bootloader mode the device will always default to the divide-by-10
option for the oscillator division ratio.
EPROM
programming
register
All necessary manipulation of this register is carried out automatically by
the bootloader routine.
ELAT — EPROM address and data latch
1 = Configures EPROM address and data buses for programming.
0 = Configures EPROM address and data buses for normal
operation.
EPGM — EPROM programming power control
1 = Switches EPROM programming power on.
0 = Switches EPROM programming power off.
A byte of EPROM is programmed using the following sequence:
set ELAT
write data to the desired EPROM address
set EPGM for time t
PROG
clear EPGM/ELAT
