state in boot mode switches to the programming control program.
by the SCI_2 (by clearing the RE and TE bits in SCR to 0), but the adjusted bit rate value
remains set in BRR. Therefore, the programming control program can still use it for transfer of
write data or verify data with the host. The TxD pin is high. The contents of the CPU general
registers are undefined immediately after branching to the programming control program.
These registers must be initialized at the beginning of the programming control program, since
the stack pointer (SP), in particular, is used implicitly in subroutine calls, etc.
least 20 states, and then setting the FWE pin and the mode (MD) pins. Boot mode is also
cleared when a WDT overflow occurs.
(for example, from low to high) during a reset, the state of ports with multiplexed address
functions and bus control output pins (AS, RD, WR) will change according to the change in
the microcomputer’s operating mode . Therefore, care must be taken to make pin settings to
prevent these pins from becoming output signal pins during a reset, or to prevent collision with
signals outside the microcomputer.
