Bits 7 to 0: SET_IMOD[8:1]. The modulation current DAC is controlled by a total of 9 bits. The SET_IMOD[8:1] bits
are used to set the modulation current with even denominations from 0 to 510 bits. The LSB (SET_IMOD[0]) is con-
trolled by the MODINC register and is used to set the odd denominations in the SET_IMOD[8:0]. Any direct write to
SET_IMOD[8:1] resets the LSB.

Bits 7 to 0: IMODMAX[7:0]. The IMODMAX register is an 8-bit register that can be used to limit the maximum modula-
tion current. IMODMAX[7:0] is continuously compared to SET_IMOD[8:1]. Any attempt to modify SET_IMOD[8:1] above
IMODMAX[7:0] is ignored and flags a warning at IMODERR.

Bits 7 to 0: IBIASMAX[7:0]. The IBIASMAX register is an 8-bit register that can be used to limit the maximum bias
current. IBIASMAX[7:0] is continuously compared to SET_IBIAS[8:1]. Any attempt to modify SET_IBIAS[8:1] above
IBIASMAX[7:0] is ignored and flags a warning at IBIASERR.

Bit 7: SET_IMOD[0]. This is the LSB of the SET_IMOD[8:0] bits. This bit can only be updated by the use of MODINC[4:0].
Bits 4 to 0: MODINC[4:0]. This string of bits is used to increment or decrement the modulation current. When written
to, the SET_IMOD[8:0] bits are updated. MODINC[4:0] are a two’s complement string.
