Bootstrap Mode
The bootstrap mode is provided in the EPROM part (MC68HC705BD3) as a mean of
self-programming its EPROM with minimal circuitry. It is entered on the rising edge of RESET if
IRQ pin is at 1.8V
DD
and PB5 is at logic one. RESET must be held low for 4064 cycles after POR
(power-on reset) or for a time t
RL
for any other reset. The user EPROM consists of 7.75K-bytes,
from location $2000 to $3EFF
Refer to Section 15 for further details on MC68HC705BD3.
