It is cleared when written with a 1. When RSA1 is set it can cause an interrupt request if the RSA1 interrupt enable
bit is set in the
RIM2 register.
Bit 2: Receive Signaling All Zeros Event (RSA0). This latched status bit is set to 1 when, over a full MF, timeslot
16 contains all zeros. It is cleared when written with a 1. When RSA0 is set it can cause an interrupt request if the
RSA0 interrupt enable bit is set in the
RIM2 register.
Bit 1: Receive CRC-4 Multiframe Event (RCMF). This latched status bit is set to 1 on CRC-4 multiframe
boundaries. It continues to be set every 2 ms on an arbitrary boundary if CRC-4 is disabled. It is cleared when
written with a 1. When RCMF is set it can cause an interrupt request if the RCMF interrupt enable bit is set in the
Bit 0: Receive Align Frame Event (RAF). This latched status bit is set to 1 approximately every 250
s to alert the
CPU that Si and Sa bits are available in the
RAF and
RNAF registers. It is cleared when written with a 1. When
RAF is set it can cause an interrupt request if the RAF interrupt enable bit is set in the
RIM2 register.

Bit 7: Loss of Receive Clock Condition Clear (LORCC). This latched status bit is set to 1 when
RRTS3- T1.LORC changes state from high to low. LORCC is cleared when written with a 1. When LORCC is set it can
cause an interrupt request if the LORCC interrupt enable bit is set in the
RIM3-T1 register.
Bit 6: Spare Code Detected Condition Clear (LSPC). This latched status bit is set to 1 when
RRTS3-T1.LSP changes state from high to low. LSPC is cleared when written with a 1. When LSPC is set it can cause an interrupt
request if the LSPC interrupt enable bit is set in the
RIM3-T1 register. See Section
10.11.14.2.
Bit 5: Loop Down Code Detected Condition Clear (LDNC). This latched status bit is set to 1 when
RRTS3- T1.LDN changes state from high to low. LDNC is cleared when written with a 1. When LDNC is set it can cause an
interrupt request if the LDNC interrupt enable bit is set in the
RIM3-T1 register. See Section
10.11.14.2.
Bit 4: Loop Up Code Detected Condition Clear (LUPC). This latched status bit is set to 1 when
RRTS3-T1.LUP
changes state from high to low. LUPC is cleared when written with a 1. When LUPC is set it can cause an interrupt
request if the LUPC interrupt enable bit is set in the
RIM3-T1 register. See Section
10.11.14.2.Bit 3: Loss of Receive Clock Condition Detect (LORCD). This latched status bit is set to 1 when
RRTS3- T1.LORC changes state from low to high. LORCD is cleared when written with a 1. When LORCD is set it can
cause an interrupt request if the LORCD interrupt enable bit is set in the
RIM3-T1 register.
Bit 2: Spare Code Detected Condition Detect (LSPD). This latched status bit is set to 1 when
RRTS3-T1.LSP changes state from low to high. LSPD is cleared when written with a 1. When LSPD is set it can cause an interrupt
request if the LSPD interrupt enable bit is set in the
RIM3-T1 register. See Section
10.11.14.2.
Bit 1: Loop Down Code Detected Condition Detect (LDND). This latched status bit is set to 1 when
RRTS3- T1.LDN changes state from low to high. LDND is cleared when written with a 1. When LDND is set it can cause an
interrupt request if the LDND interrupt enable bit is set in the
RIM3-T1 register. See Section
10.11.14.2.
Bit 0: Loop Up Code Detected Condition Detect (LUPD). This latched status bit is set to 1 when
RRTS3-T1.LUP
changes state from low to high. LUPD is cleared when written with a 1. When LUPD is set it can cause an interrupt
request if the LUPD interrupt enable bit is set in the
RIM3-T1 register. See Section
10.11.14.2.
