3.2 Introduction
The MC68HC705P6A has two modes of operation that affect the pinout
and architecture of the MCU: user mode and bootloader mode. The user
mode is normally used for the application and the bootloader mode is
used for programming the EPROM. The conditions required to enter
each mode are shown in
Table 3-1
. The mode of operation is
determined by the voltages on the IRQ/V
PP
and PD7/TCAP pins on the
rising edge of the external RESET pin.
