R N/A MAX705 supervisor detects VCC < 4.65V.
R N/A RTS reset request from host via comm line.
R N/A Push button pressed.
R N/A Expansion room, reads as '1'.
R N/A Expansion room, reads as '1'.
R N/A Expansion room, reads as '1'.
R N/A Write to the suicide register, read suicide reg for error code.
R N/A Scanner reset register latched, read scanner reg for error code.
The CPU Reset SFR is a byte register into which the CPU can write a failure
code. In response to the write the MAX PLD will store the failure code and
assert the CPU_RESET line. The CPU_RESET line will be released on the
next rising edge of the host RTS, at which time the CPU will be able to read
the bit code from this SFR to determine the cause of the previous reset.
The misc. output register is used to control the misc. output functions listed in
the following table.
R/ Def. Description
W
N/A N/A Expansion room.
R/W 0 Firmware controlled diagnostic LED.
R/W 0 Enable direct connect of host and DMB XCVR's, bypassing
UART's, for maximized scan data bandwidth DMB to host.
R/W 1 Enable override of CPU_RESET signal. Set to 1 on power-up such
that firmware can load the FLEX PLD at power-up regardless of
the host RTS state.
