RFCLKA

RFCLKA:

The RFCLKA bit monitors for low to high transitions on the RFCLK input.

RFCLKA is set high on a rising edge of RFCLK, and is set low when this

TFCLKA:

The TFCLKA bit monitors for low to high transitions on the TFCLK input.

TFCLKA is set high on a rising edge of TFCLK, and is set low when this

TICLKA:

The TICLKA bit monitors for low to high transitions on the TICLK[x] input.

TICLKA is set high on a rising edge of TICLK[x], and is set low when this

RCLKA:

The RCLKA bit monitors for low to high transitions on the RCLK[x] input.

RCLKA is set high on a rising edge of RCLK[x], and is set low when this

INT[4:1]:

The INT[4:1] bits identify which of the four quadrants of the S/UNI-QJET have

generated the current interrupt. When the INT[x] bit is set to logic 1, then the

Xth quadrant has generated the interrupt. The particular block(s) within that
