4.2.17 Boot Loader and Passcode Management – Available with the LAPI-*BL.lib Only
The Boot Loader code occupies the first (lower) 512 bytes of the Flash program space (0x0000 - 0x01FF)
including the passcode storage space. The Boot Loader assumes that the CPU is running at the default
clock rate which is 3.69 MHz. As a result, the serial baud rate and all soft-timers (timer 0) are calculated
based on the default CPU clock rate. The Boot Loader also only accepts Intel Hex files via the Serial
RS-232 interface. The Boot Loader and Passcode Management API include:
CheckPassCode () (page 68)
SetPassCode ( ) (page 69)
For security and authorization enforcement, the passcode is implemented, embedded and validated
within the Boot Loader code. The Boot Loader will return a hardware error if Security Mode 0 or Security
Mode 1 has already been enabled. Figure 9 depicts a successful Boot Loader scenario.

Figure 9: Boot Loader Scenario
The Passcode is a 2-byte integer data type where the second byte is the complement of the first byte.
After validating the Passcode, the LAPI will configure the device’s serial interface to be running at 115200
baud with 8 data bits, No stop bit and Xon/Xoff control enabled. It then waits for a valid Intel hex
record from the Serial RS-232 interface. The record’s checksum is checked along with its Flash address
location. The Boot Loader code area (the first page of Flash – 512 bytes at address 0x0000 – 0x01FF)
will be protected. Any hex record with addresses on the first page will be ignored. Once a valid hex
record is accepted by the device, all Flash space (except for the Boot Loader area) will be permanently
erased. For each successful hex record received by the device, the device will respond with a ‘P’. For
each failed hex record received by the device (bad CRC), the device will respond with an ‘F’. When the
device receives the last successful hex record and if there is no error, the device will immediately jump to
the start of the new application. For a sample of the usage of the Boot Loader API, review the
Pseudo-CCID application code (built and shipped in a separate TSC 73S12xxF PCCID Serial release).
