HF and PAF flags begin with the rising edge of RCLK that RT is setup.
PAE is synchronized to RCLK, thus on the second rising edge of RCLK
after RT is setup, the PAE flag will be updated. HF is asynchronous,
thus the rising edge of RCLK that RT is setup will update HF. PAF is
synchronized to WCLK, thus the second rising edge of WCLK that
