Bootstrap Mode
The Bootstrap mode is provided in the EPROM part (MC68HC705SR3) as a mean of
self-programming its EPROM with minimal circuitry. Bootstrap mode will be entered on the rising
edge of RESET when the VPP pin is at VTST (2×VDD) and PB1 pin is at VDD. Once in the bootstrap
mode, PB1 can then be used for other purposes. After entering the bootstrap mode, CPU
branches to the bootstrap program and carries out the EPROM programming routine. The user
EPROM consists of 3840 bytes, from location $1000 to $1EFF.
Refer to Appendix A for further details on MC68HC705SR3.
