(1)
A = (ACLKX period)/2 in ns. For example, when ACLKX period is 25 ns, use A = 12.5 ns.
(2)
AH = (AHCLKX period)/2 in ns. For example, when AHCLKX period is 25 ns, use AH = 12.5 ns.

ACLKX internal: ACLKXCTL.CLKXM=1, PDIR.ACLKX = 1
ACLKX external input: ACLKXCTL.CLKXM=0, PDIR.ACLKX=0
ACLKX external output: ACLKXCTL.CLKXM=0, PDIR.ACLKX=1
ACLKX external input: ACLKXCTL.CLKXM=0, PDIR.ACLKX=0
ACLKX external output: ACLKXCTL.CLKXM=0, PDIR.ACLKX=1
