Program Registers
The 'Program registers’ are used for device configuration settings and are typically programmed once on
powerup or after device reset. There are different program registers such as ‘Auto-1 mode programming’ for
pre-programming the channel sequence, ‘Auto-2 mode programming’ for selection of the last channel in the
sequence, ‘Alarm programming’ for all 16 channels (or 12,8,4 channels depending on the device) and GPIO for
individual pin configuration as GPI or GPO or a pre-assigned function.
DEVICE POWER-UP SEQUENCE
The device power-up sequence is shown in Figure 49. Manual mode is the default power-up channel sequencing
mode and Channel-0 is the first channel by default. As explained previously, these devices offer Program
Registers to configure user programmable features like GPIO, Alarm, and to pre-program the channel sequence
for Auto modes. At ‘powerup or on reset’ these registers are set to the default values listed in Table 1 to
Table 10. It is recommended to program these registers on powerup or after reset. Once configured; the device
is ready to use in any of the three channel sequencing modes namely Manual, Auto-1, and Auto-2.
