- Parses the DTC vector table described by the manual and decodes DTC register-information blocks.
- Tracks SCI setup writes and can infer baud rates from SMR/BRR when `--clock-hz` is supplied.
- Annotates SCI protocol actions such as TDRE waits, TDR writes, RDR reads, RX/TX interrupt enables, and receive-error clears.
- Reconstructs evidence-supported SCI1 serial frame candidates, including the apparent six-byte TX/RX units and XOR checksum seeded by `0x5A`.
- Adds a Sony RCP-TX7 board profile that ties H8/536 pin 66 `P95/TXD` and pin 67 `P96/RXD` to the MAX202 RS232 transceiver.
- Flags/manual-annotates TEMP-register access ordering for FRT and A/D 16-bit peripheral registers.
- Scans unreached ROM ranges for ASCII strings and pointer-table candidates.
