Tpd and Tpu Timing
These timing parameters are mostly designed for Class I boards, although the
delays are valid for all classes of boards. Many of the ICS boards and user
target boards need time to power down and power up.
Whenever power is automatically switched off, or is manually requested to be
switched off, the software waits for an amount of time equal to the Tpd delay
time before proceeding to the connection protocol. This is because a board or
power supply may have capacitance which holds the power up for a short time
after the supply has been switched off, but the supply voltage must reach less
than 0.1v before it is turned back on if a Power-On reset is to occur.
Whenever power is automatically switched on, or is manually requested to be
switched on, the software waits for an amount of time equal to the Tpu delay
time before attempting to contact the 68HC08 processor. This is to allow time
not only for power to be fully available, but to wait until any reset driver has
finally released the RESET line. On many ICS08 boards (such as the
ICS08RK, M68ICS08JL3, M68ICS08JLJK, and ICS08GP20) the Tpu can be
decreased to as little as 250ms with no adverse effects.
Target has RESET button (class III boards only): The software
occasionally needs to get control of the target. On systems which are Class III
boards with the monitor mode circuitry built-in (including RS-232 driver),
there is no means to reset the target to gain control. If the board has a reset
button, the software can use this to gain control of the target system. If this
option is checked, the software will prompt the user to push the target reset
button when a reset of the target system is desired. If the option is unchecked,
the software will ask the user to power cycle the target system to achieve a
