switches to the programming control program. Figure 23.8 shows the on-chip RAM area in
boot mode.
LSI terminates transfer operations by the SCI_1 (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 TxD1 pin is
in high-level output state. 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.

from low to high during reset, operating modes are switched and the state of ports that are also
used for address output and bus control output signals (AS, RD, and HWR) are changed *
Therefore, set these pins carefully not to be output signals during reset or not to conflict with
LSI external signals.
