Table 161. Register 0xFE3E/41/44/47/4A/4D—OUTA/OUTB/OUTC/OUTD/SR1/SR2 Rising Edge Timing

Bits

Bit Name/Function

R/W

Description

[7:0]

Rising edge timing, tRx,

MSBs

R/W

This register contains the eight MSBs of the 12-bit tRx time. This value is always used with the top

four bits of Register 0xFE40, Register 0xFE43, Register 0xFE46, Register 0xFE49, Register 0xFE4C,

and Register 0xFE4F, which contain the four LSBs of the tRx time.

tRx represents tR1, tR2, tR3, tR4, tR5, and tR6. Each LSB corresponds to 5 ns resolution.

Bits

Bit Name/Function

R/W

Description

[7:0]

Falling edge timing, tFx,

MSBs

R/W

This register contains the eight MSBs of the 12-bit tFx time. This value is always used with the

bottom four bits of Register 0xFE40, Register 0xFE43, Register 0xFE46, and Register 0xFE49, as

well as Register 0xFE4C and Register 0xFE4F, which contain the four LSBs of the tFx time.

tFx represents tF1, tF2, tF3, tF4, tF5, and tF6. Each LSB corresponds to 5 ns resolution.

Bits

Bit Name/Function

R/W

Description

[7:4]

Rising edge timing, tRx,

LSBs

R/W

These bits contain the four LSBs of the 12-bit tRx time. This value is always used with the eight bits of

and Register0xFE4D, which contain the eight MSBs of the tRx time.

tRx represents tR1, tR2, tR3, tR4, tR5, and tR6. Each LSB corresponds to 5 ns resolution.

[3:0]

Falling edge timing, tFx,

LSBs

R/W

These bits contain the four LSBs of the 12-bit tFx time. This value is always used with the eight bits

of Register 0xFE3F, Register 0xFE42, Register 0xFE45, and Register 0xFE48, as well as Register 0xFE4B

and Register 0xFE4E, which contain the eight MSBs of the tFx time.

tFx represents tF1, tF2, tF3, tF4, tF5, and tF6. Each LSB corresponds to 5 ns resolution.
