Register 0xE0: RASE Interrupt Enable
| Bit | Type | Function | Default | 
| Bit 7 | R/W | PSBFE | 0 | 
| Bit 6 | R/W | COAPSE | 0 | 
| Bit 5 | R/W | Z1/S1E | 0 | 
| Bit 4 | R/W | SFBERE | 0 | 
| Bit 3 | R/W | SDBERE | 0 | 
| Bit 2 | R/W | Unused | X | 
| Bit 1 | R/W | Unused | X | 
| Bit 0 | R/W | Unused | X | 
SDBERE:
The SDBERE bit is the interrupt enable for the signal degrade threshold alarm. When SDBERE is a logic one, an interrupt is generated when the SD alarm is declared or removed.
SFBERE:
The SFBERE bit is the interrupt enable for the signal fail threshold alarm. When SFBERE is a logic one, an interrupt is generated when the SF alarm is declared or removed.
Z1/S1E:
The Z1/S1 interrupt enable is an interrupt mask for changes in the received synchronization status. When Z1/S1E is a logic one, an interrupt is generated when a new synchronization status message is extracted into the Receive Z1/S1 register.
COAPSE:
The COAPS interrupt enable is an interrupt mask for changes in the received APS code. When COAPSE is a logic one, an interrupt is generated when a new K1/K2 code value is extracted into the RASE Receive K1 and RASE Receive K2 registers.
PSBFE:
The PSBF interrupt enable is an interrupt mask for protection switch byte failure alarms. When PSBFE is a logic one, an interrupt is generated when PSBF is declared or removed.
