ACLR

Bits[14:3]

ACLRn: Auto clear DAC-n enable bit.

If ACLRn = '1', DAC-n is forced into a clear state when the alarm occurs.

If ACLRn = '0', DAC-n is not forced into a clear state when the alarm occurs (default).

NOTE

ACLRn is always ignored when an alarm occurs for a temperature greater than +150°C

(THERM-ALR = '1'). If an alarm activates for a temperature greater than +150°C, and if

the THERM-ALR-CLR bit in the AUTO-DAC-CLR-SOURCE Register is set ('1'), all DACs

are forced into a clear status. However, if THERM-ALR-CLR is cleared ('0'), the over

+150°C alarm does not force any DAC to a clear status.

SW-DAC-CLR REGISTER (Read/Write, Address = 55h, Default = 0000h)

This register uses software to force the DAC into a clear state.

ICLR

Bits[14:3]

ICLRn: Software clear DACn bit.

If ICLRn = '1', DACn is forced into a clear state.

If ICLRn = '0', DACn is restored to normal operation.

HW-DAC-CLR-EN 0 REGISTER (Read/Write, Address = 56h, Default = 0000h)

This register determines which DAC is in a clear state when the DAC-CLR-0 pin goes low.

H0CLR

Bits[14:3]

H0CLRn: Hardware clear DAC-n enable 1 bit.

If H0CLRn = '1', DAC-n is forced into a clear state when the DAC-CLR-0 pin goes low.

If H0CLRn = '0', pulling the DAC-CLR-0 pin low does not effect the state of DAC-n.
