The default setting is "AUTO MODE", which means that the time between
the falling edge of the BUSY signal and the rising edge of the STROBE signal
is measured, and if it is longer than about 33 µ sec, the mode is automatically
switched to the LOW SPEED MODE; if it is shorter, the mode is automatically
switched to the HIGH SPEED MODE.
It is also possible to fix the mode to the LOW SPEED MODE by sending a
command from the PC to rewrite the contents of the NV-RAM.
BUSY goes HIGH at the falling edge of STROBE.
The data (8-bit) from the PC is latched in the ASIC at the rising edge of
STROBE.
The pulse width of ACK differs according to the MODE, as shown above.
(8) Software support
Supports 16 x 16 rotation, bit expansion, and floating decimal point calculations.
(9) EEPROM I/O
One output port and one I/O port are assigned.
