REG_SIGN (base+0): Signature (read only)

Always reads 8Ch. Can be used by software to verify the presence of a module with register interface.

REG_MODEL (base+1): PV-1800 firmware model number (read only)

When the firmware is changed to remove, add, or change features, the model number is changed. Current model number is 00h.

REG_DIGOUT (base+2): Digital outputs (read/write)

Writing to bit 0-6 sets digital output 0-6. 0=off, 1=on.

Reading bit 0-6 returns the current status of digital output 0-6.

Bit 7 is always 0.

REG_DIGIN (base+3): Digital inputs (read only)

Reading bit 0-7 returns the current status of digital input 0-7. 0=off, 1=on.

DI0 and DI1 can also be used as counter inputs. Regardless of this, their current status can always be read at this register.

REG_CNTLO (base+4): Counter low byte (read only)

Reading this register returns bit 0-7 of the current value of the counter, and simultaneously stores bit 8-15 of the counter in the REG_CNTHI register.

REG_CNTHI (base+5): Counter high byte (read only)

Reading this register returns the previously stored value of bit 8-15 of the counter.
