In the second method, the MODB/V
backup or from a second power supply, as shown in Figure 4-3. Using the MODB/
V
amount of external circuitry is operating from V
contents, reset must be held low whenever V
to SECTION 5 RESETS AND INTERRUPTS.
The four operating modes are selected with the logic states of the mode A (MODA)
and mode B (MODB) pins during reset. The MODA and MODB logic levels determine
the logic state of the special mode (SMOD) and mode A (MDA) control bits in the
HPRIO register.
After reset is released, the mode select pins no longer influence the MCU operating
mode. For single-chip mode, the MODA pin is connected to a logic zero. For expanded
mode, MODA is normally connected to V
MODA pin also functions as the load instruction register (LIR) pin when the MCU is not
in reset. The open drain active low LIR output pin drives low during the first E cycle of
each instruction. The MODB pin also functions as standby power input, V
maintains RAM contents in the absence of V
