Register 02H: Input Signal Activity Monitor
This register provides activity monitoring on major TUPP inputs. When a
monitored input makes a low to high transition, the corresponding register bit is
set high. The bit will remain high until this register is read, at which point, all the
bits in this register are cleared. A lack of transitions is indicated by the
corresponding register bit reading low. This register should be read at
periodically to detect for stuck at conditions.

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
The SCLK active (SCLKA) bit monitors for low to high transitions on the SCLK
input. SCLKA is set high on a rising edge of SCLK, and is set low when this
register is read.
The IC1J1 active (IC1J1A) bit monitors for low to high transitions on the IC1J1
input. IC1J1A is set high on a rising edge of IC1J1, and is set low when this
register is read.
The ISPE active (ISPEA) bit monitors for low to high transitions on the ISPE
input. ISPEA is set high on a rising edge of ISPE, and is set low when this
register is read.
