Watchdog Timer

These are all integer (16 bit) types. Function code 3 reads, 16 writes.

30 Read or write Watchdog timeout value.

0 = disable watchdog

1-255 = Timeout seconds.

Read or write

Watchdog timer value. This register increments every second until it

matches the value in Register 30 or until a 0 is written to this register.

Non-Volatile Intgeger storage

These are integer (16 bit) types. Function code 3 reads, 16 writes. Address range is 4001 to 4256, inclusive

. These registers

retain data when power is removed from the board. These registers may be set to 0 by writing a 0 to register 4802 and

resetting the board. Note that writing a 0 to 4802 also clears floating point non-volatile registers.

Volatile Integer storage

These are integer (16 bit) types. Function code 3 reads, 16 writes.

Address range is 4501 to 4628. These registers reset to 0

on power up or CPU reset (manual or watchdog timeout).
