RFPO/RMFPO
Output AB5
Framer Receive Frame Pulse/Multi-frame Pulse
(RFPO/RMFPO). RFPO/RMFPO is valid when the
TEMAP is configured to be in framer only mode by
setting the OPMODE[1:0] bits in the Global
Configuration register.
RFPO is aligned to RDATO and indicates the position
of the first bit in each DS3 M-subframe.
RMFPO is aligned to RDATO and indicates the
position of the first bit in each DS3 M-frame. This is
selected by setting the RXMFPO bit in the Master
Framer Configuration Registers.
RFPO/RMFPO is updated on either the falling or rising
edge of RSCLK depending on the setting of the
RSCLKR bit in the DS3 Master Unchannelized
Interface Options register.
This signal shares a signal pin with IFP[1]. When
enabled for unchannelized DS3 operation this signal
will be RFPO/RMFPO, otherwise it will be IFP[1].
ROVRHD
Output Y6
Framer Receive Overhead (ROVRHD). ROVRHD is
valid when the TEMAP is configured as a DS3 framer
by setting the OPMODE[1:0] bits in the Global
Configuration register.
ROVRHD will be high whenever the data on RDATO
corresponds to an overhead bit position. ROVRHD is
updated on the either the falling or rising edge of
RSCLK depending on the setting of the RSCLKR bit in
the DS3 Master Unchannelized Interface Options
register.
This signal shares a signal pin with ID[2]. This signal
will be ROVRHD only when enabled for unchannelized
DS3 operation.
