18.10.1 Serial Communication Interface Specification for Boot Mode
Initiating boot mode enables the boot program to communicate with the host by using the internal
SCI. The serial communication interface specification is shown below.
The boot program has three states.
(1) Bit-Rate-Adjustment State
(2) Inquiry/Selection State
(3) Programming/erasing state
These boot program states are shown in figure 18.23.
Rev. 2.0, 06/04, page 646 of 980
Status
In this state, the boot program adjusts the bit rate to communicate with the host. Initiating
boot mode enables starting of the boot program and entry to the bit-rate-adjustment state. The
program receives the command from the host to adjust the bit rate. After adjusting the bit rate,
the program enters the inquiry/selection state.
In this state, the boot program responds to inquiry commands from the host. The device name,
clock mode, and bit rate are selected. After selection of these settings, the program is made to
enter the programming/erasing state by the command for a transition to the
programming/erasing state. The program transfers the libraries required for erasure to the
RAM and erases the user MATs and user boot MATs before the transition.
Programming and erasure by the boot program take place in this state. The boot program is
made to transfer the programming/erasing programs to the RAM by commands from the host.
Sum checks and blank checks are executed by sending these commands from the host.
