RXMFPO

The RXMFPO bit controls which of the outputs RMFPO or RFPO is valid. If RXMFPO is a

logic one, then RMFPO will be available. If RXMFPO is a logic zero, then RFPO will be

available. This bit is effective only if the FRMRONLY bit in the S/UNI-JET Configuration 1

TXMFPO

The TXMFPO bit controls which of the outputs TMFPO[4:1] or TFPO[4:1] is valid. If

TXMFPO is a logic one, then TMFPO[4:1] will be available. If TXMFPO is a logic zero,

then TFPO[4:1] will be available. This bit is effective only if the FRMRONLY bit in the

S/UNI-JET Configuration 1 Register is a logic one. The TXGAPEN bit takes precedence over

the TXMFPO bit.

RXGAPEN

The RXGAPEN bit configures the S/UNI-JET to enable the RGAPCLK[x] outputs. When

RXGAPEN is a logic one, then the RGAPCLK[x] output is enabled. When RXGAPEN is a

logic zero, then the RSCLK[x] output is enabled. The FRMRONLY register bit must be a

logic one for RXGAPEN to have effect.

TXGAPEN

The TXGAPEN bit configures the S/UNI-JET to enable the TGAPCLK[x] outputs. When

TXGAPEN is a logic one, the TGAPCLK[x] output is enabled. When TXGAPEN is a logic

zero, then either the TFPO[x] or TMFPO[x] output is enabled, depending on the setting of the

TXMFPO register bit. The FRMRONLY register bit must be a logic one for TXGAPEN to

have effect.
