JPEG Indirect Registers
Micron Confidential and Proprietary
GPIO_WG_T35 7:0
Fourth subperiod of waveform output at GPIO5 (in 8-bit counter
mode) or bits 15:8 of fourth subperiod of waveform output at
GPIO4 (in 16-bit counter mode).
109E 0
GPIO_WG_T34 7:0
Fourth subperiod of waveform generated at GPIO4 (in 8-bit
counter mode) or bits 7:0 of the same (in 16-bit counter mode).
109F 0
GPIO_WG_T45 7:0
Fifth subperiod of waveform output at GPIO5 (in 8-bit counter
mode) or bits 15:8 of fifth subperiod of waveform output at GPIO4
(in 16-bit counter mode).
10A0 0
GPIO_WG_T44 7:0
Fifth subperiod of waveform generated at GPIO4 (in 8-bit counter
mode) or bits 7:0 of the same (in 16-bit counter mode).
10A1 0
GPIO_WG_N5 7:0
Writing to this register sets the duration of waveform generated at
GPIO5 (in 8-bit counter mode) or bits 15:8 of the duration of
waveform generated at GPIO4 (in 16-bit counter mode). Finite
duration is selected by writing the desired number of periods in the
waveform. Writing “0” makes the duration infinite.
When read, this registers returns the number of waveform periods
left to be generated at GPIO5 (in 8-bit counter mode) or bits 15:8 of
the number remaining at GPIO4 (in 16-bit counter mode). To get all
16 bits of the latter number right, one must read this register
before GPIO_WG_N4.
10A2 0
GPIO_WG_N4 7:0
Writing to this register sets the duration of waveform generated at
GPIO4 (in 8-bit counter mode) or bits 7:0 of the same (in 16-bit
counter mode). Finite duration is selected by writing the desired
number of periods in the waveform. Writing “0” makes the
duration infinite.
When read, this registers returns the number of waveform periods
left to be generated at GPIO4 (in 8-bit counter mode) or bits 7:0 of
the same (in 16-bit counter mode).
10A3 0
GPIO_WG_T07 7:0
First subperiod of waveform generated at GPIO7 (in 8-bit counter
mode) or bits 15:8 of first subperiod of waveform output at GPIO6
(in 16-bit counter mode).
10A4 0
GPIO_WG_T06 7:0
First subperiod of waveform generated at GPIO6 (in 8-bit counter
mode) or bits 7:0 of the same (in 16-bit counter mode).
10A5 0
GPIO_WG_T17 7:0
Second subperiod of waveform output at GPIO7 (in 8-bit counter
mode) or bits 15:8 of second subperiod of waveform output at
GPIO6 (in 16-bit counter mode).
10A6 0
GPIO_WG_T16 7:0
Second subperiod of waveform generated at GPIO6 (in 8-bit
counter mode) or bits 7:0 of the same (in 16-bit counter mode).
10A7 0
GPIO_WG_T27 7:0
Third subperiod of waveform output at GPIO7 (in 8-bit counter
mode) or bits 15:8 of third subperiod of waveform output at GPIO6
(in 16-bit counter mode).
10A8 0
GPIO_WG_T26 7:0
Third subperiod of waveform generated at GPIO6 (in 8-bit counter
mode) or bits 7:0 of the same (in 16-bit counter mode).
10A9 0
GPIO_WG_T37 7:0
Fourth subperiod of waveform output at GPIO7 (in 8-bit counter
mode) or bits 15:8 of fourth subperiod of waveform output at
GPIO6 (in 16-bit counter mode).
10AA 0
GPIO_WG_T36 7:0
