bit 7-4
CHANNEL_N_OFF[3:0]:
Allow one or more channels to be disabled (bit value = 1) during the conversion cycle. A bit value = 0
means the channel is active. These settings apply for normal continuous round robin conversion
cycles or Single-Shot mode, if Single-Shot mode is selected. If a channel is set to inactive, the
auto-incrementing address pointer will skip addresses associated with that channel unless the No Skip
bit 1 in Register 7-10 is set.
Channel 1: bit 3
Channel 2: bit 2
Channel 3: bit 1
Channel 4: bit 0
Example: Channel 2 disabled, Channel 1, 3 and 4 enabled. CHANNEL_N_OFF = 0b0100.
In PAC194X devices, deactivating channels allows faster sampling. Burst or Fast modes are selected
using bits [15:12] in this register.
PAC1944-1 default = 0b0000 (register default 0700h) (shown above)
PAC1943-1 default = 0b0001 (register value 0710h)
PAC1942-1 default = 0b0011 (register value 0730h)
PAC1942-2 default = 0b0011 (register value 0730h)
PAC1941-1 default = 0b0111 (register value 0770h)
PAC1941-2 default = 0b0111 (register value 0770h)
