The MX function is used with PALs and some discrete devices.
MXSYNC# is clocked out using the falling edge of MXCLK and MXDO
by using the rising edge of the MXCLK. MXDI is sampled at the rising
edge of MXCLK (the transition module synchronizes MXDI with
MXCLK's rising edge). The timing relationships among MXCLK,
MXSYNC#, MXDO, and MXDI are shown in
MXDI
