(3) UART data transfer format
Table 3.4.6 to Table 3.4.11 show the supported frequencies, data transfer format, baud
rate modification command, operation command, and version management
information, respectively.
Please also refer to the description of boot program operation later in this section.
Note: The built-in PLL (clock multiplier) is not used regardless of the oscillation frequency.

"Error code x 3" means that the error code is transmitted three times. For example, if the error code is 62H, the
TMP92CZ26A transmits 62H three times. For error codes, see (4)-b).
