1.3 Mask Options
Stop disable is a mask programmable option on MC68HC05CJ4.
There are no mask programmable options on MC68HC705CJ4.
1.4 Signal Description
This section mainly describes signals in the single-chip mode or the user mode.
See Figure 1-3.
1.4.1 VDD and VSS
The power is supplied to the microcontroller using VDD and VSS. VDD is the positive
supply, and VSS is ground. For more detailed information refer to 14.6 DC
Operating Characteristics.
1.4.2 RESET
This pin is used to reset the MCU and provide an orderly start-up procedure by
pulling RESET low. The RESET and power-on reset (POR) functions do not
