Register 009H: NSE-8G Master Clock Monitor
When a monitored clock signal 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 periodic intervals to detect clock failures.

The SYSCLK active bit (SYSCLKA) detects low to high transitions on the SYSCLK input.
SYSCLKA is set high on a rising edge of SYSCLK, and is set low when this register is read.
The RC1FP active bit (RC1FPA) detects low to high transitions on the RC1FP input.
RC1FPA is set high on a rising edge of RC1FP, and is set low when this register is read.
