Control Register (address 0x19)
The Control Register controls the signal pattern generator and the interrupt and acknowledge pin behavior. It
specifies the interrupt and acknowledge pin polarities, the master interrupt enable and the signal pattern
generator length.
Table 20
shows the Control Register.
Pattern Register (address 0x1A)
The shift register of the signal generator is written through the Pattern Register. Each time this register is written,
the shift register is shifted 16 bits upwards and the written data is stored in the 16 LSBs of the shift register. The
Pattern Register is a write-only register; a read always returns 0x0000.
Table 21
describes the Pattern Register.

DESCRIPTION
Acknowledge polarity for pin ACK.
0: New data is signaled with a '1' on the pin ACK
1: New data is signaled with a '0' on the pin ACK
Interrupt polarity for pin INT.
0: An interrupt is signaled with a positive transition on the pin INT
1: An interrupt is signaled with a negative transition on the pin INT
Master interrupt enable.
0: Interrupt pin and interrupt flags are blocked (interrupt pin INT always inactive).
1: Interrupt pin and interrupt flags are not blocked and can be set and reset (if individually
enabled).
Unused. Always read '0'.
Pattern count.
Defines the length of the shift register for the signal generator
