Technical Data MC68HC908JB8•MC68HC08JB8•MC68HC08JT8 — Rev. 2.3
282 MC68HC08JT8 Freescale Semiconductor
B.8 Monitor ROM
The monitor program (monitor ROM: $FE10–$FFDF) on the
MC68HC08JT8 is for device testing only. $FC00–$FDFF are unused.
B.9 Universal Serial Bus Module
The USB module is designed for operation with V
DD
= 4V to 5.5V,
therefore, it should not be used on the MC68HC08JT8 device. To further
reduce current consumption in stop mode, set the SUSPND bit in the
USB interrupt register 0 (UIR0) to logic 1. Other USB registers should be
left in their default state.
B.10 Low-Voltage Inhibit Module
The LVI module is disabled on the MC68HC08JT8.
B.11 Electrical Specifications
