11.2 Introduction
The MCU has two modes of operation: user mode and self-check mode.
Table 11-1
shows the conditions required to enter into each mode,
where V
TST
= 2 x V
DD
.
11.3 User Mode
In user mode, the address and data buses are not available externally,
but there are three 8-bit I/O ports and one 7-bit input-only port. This
mode allows the MCU to function as a self-contained microcontroller,
with maximum use of the pins for on-chip peripheral functions. All
address and data activity occurs within the MCU. User mode is entered
on the rising edge of RESET if the IRQ pin is within normal operating
range.
