MAX3798/MAX3799 register. After either V CC exceeds POA (after a POR event), the MAX3798/MAX3799 TX_POR
bit is set high (visible in 3W TXSTAT1, Bit 7) or on a rising edge of TXD, this value is written to the MAX3798/
MAX3799 through the 3-wire interface.

MAX3798/MAX3799 register. After either V CC exceeds POA (after a POR event), the MAX3798/MAX3799 TX_POR
bit is set high (visible in 3W TXSTAT1, Bit 7) or on a rising edge of TXD, this value is written to the MAX3798/
MAX3799 through the 3-wire interface. In addition, this value defines the maximum DAC value allowed for the
upper 8 bits of BIAS output during APC closed-loop operations. During the intial step and binary search, this
value does not cause an alarm but still clamps the BIAS register value. After the startup seqence (or normal
APC operations), if the APC loop tries to create a BIAS value greater than this setting, it is clamped and creates
a MAX BIAS alarm.
