Boot Loader

Boot ROM is a 256-word ROM mapped in program space 0000h?00FFh. This ROM will be enabled if the
BOOT_EN mode is enabled during reset. Boot-enable function is implemented using combinational logic of the
TDI, TRST, and RS pins as described below. The on-chip bootloader is invoked when:
TRST = 0
RS = 0
TDI = 0
(In addition to the three pins mentioned above, the application must ensure that PDPINTA stays high during the
execution of the boot ROM code.) Since it has an internal pulldown, the TRST pin will be low, provided the JTAG
connector is not connected. Therefore, the BOOT_EN bit (bit 3 of the SCSR2 register) will be set to 0 if TDI is
low upon reset. If on-chip bootloader is desired while debugging with the JTAG connector connected
(TRST = 1), it can be achieved by writing a “0” into bit 3 of the SCSR2 register.
