At initial power-on to the MCU, there is a delay of a few hundred milliseconds
during which the signal ICS_RST# is held low, as set by U8 (DS1233).
When ICS_RST# goes high, the binary ripple counter, U3, begins counting
clock cycles, at the 9.8304MHz rate of the clock Y1. After 1024 clock cycles
are counted, the DELAY_RESET signal toggles and the counter stops counting.
The delayed reset signal is used to turn-on communications to the MCU and to
hold several MCU pins in appropriate states to force Monitor Mode on
power-up.
Serial communication in half-duplex mode, using PTA0 for transmit and
receive, to the MCU is via the DE9 connector, J6. Pin 2 is the path for transmit
signals and pin 3 is for receive signals. Pin 4, the DTR signal, is utilized as an
input to provide the software host with the ability to turn MCU power on and
off. The RTS signal on contact 7 is used as an input to provide the software host
with the ability to control the IRQ* high voltage.
Serial communication to the MCU does not occur until DELAY_RESET
becomes active high 1024 clock cycles after the RESET signal is high (para
3.4.1.3).
The source of timing for the MCU may be either the KXICS board’s clock Y1
or the MCU’S internal clock. Selection is by jumper header W-4 (Table 2-1).
