Function
Each bit is used to mask an alarm. Assertion masks the alarm:
bit15 = always set to "1"
bit14 = always set to "1"
bit13 = mask SYSREF errors on link1
bit12 = mask SYSREF errors on link0
bit11 = mask alarm from PAP A block
bit10 = mask alarm from PAP B block
bit9 = mask alarm from PAP C block
bit8 = mask alarm from PAP D block
bit7 = reserved
bit6 = reserved
bit5 = reserved
bit4 = reserved
bit3 = mask alarm from SerDes block 0 PLL lock
bit2 = mask alarm from SerDes block 1 PLL lock
bit1 = mask SYSREF setup/hold measurement alarm
bit0 = mask DAC PLL lock alarm

15:0 alarms_mask(47:32)
Each bit is used to mask an alarm. Assertion masks the alarm:
bit15 = mask alarm from lane7 short test
bit14 = mask alarm from lane6 short test
bit13 = mask alarm from lane5 short test
bit12 = mask alarm from lane4 short test
bit11 = mask alarm from lane3 short test
bit10 = mask alarm from lane2 short test
bit9 = mask alarm from lane1 short test
bit8 = mask alarm from lane0 short test
bit7 = mask alarm from lane7 loss of signal detect
bit6 = mask alarm from lane6 loss of signal detect
bit5 = mask alarm from lane5 loss of signal detect
bit4 = mask alarm from lane4 loss of signal detect
bit3 = mask alarm from lane3 loss of signal detect
bit2 = mask alarm from lane2 loss of signal detect
bit1 = mask alarm from lane1 loss of signal detect
bit0 = mask alarm from lane0 loss of signal detect
