The version byte can hold values of 0x00 – 0x7f.

The GPIO count byte encodes the GPIO count in its lower nibble according to table 4.

GPIO count byte value GPIO count

0x0 14

0x1 49

0x2 64

0x3 192

Table 4: GPIO count encoding

4.7.2 TYP – Pin type set-up

Function Sets pin type for the pin range x to y and remove all links that

are in place

Command byte 0x82

Argument list First pin address to change, last pin address to change, pin type

Example arguments 0x01 0x00 | 0x7f 0x00 | 0x03 (Deﬁne pins P1 to P127 as outputs)

If the last pin number equals 0, only one pin state will be changed.

The pin type can be any of the ones listed in table 5.

Pin type Function

0x00 Low impedance / tristate

0x03 Output (Low initially)

4.7.3 REA – Read register

Function Read register address

Command byte 0xC7

Argument list 0x27 <addr> 0x00 0x00

Reply argument list Register value

Example arguments 0x27 0x7f 0x00 0x00 (Read status register)

To read a register, use 0x27 as ﬁrst argument byte, the register address according to table

6 as second byte, followed by 0x00 0x00.

The 7-bit register value will be returned in a single byte.
