6.2 Introduction
The normal operating mode of the MC68HC(8)05PV8/A is user (or
single chip) mode. There is also a monitor mode, primarily for
programming and evaluation purposes. In addition to these modes,
there are two low power modes which may be entered and exited at will
from user mode: STOP and WAIT. Table 6-1 shows the conditions
required to enter the modes of operation on the rising edge of RESET,
where VTST = 2 x VDD.
