3.5.12
The Independent mode can be used where one
encoder is used to control two receivers. Two counters
(SYNC_A and SYNC_B) are used in Independent
mode. As indicated in Table 3-9, function codes 1 to 7
use SYNC_A and 8 to 15 SYNC_B.
3.5.13
The Independent mode also selects IR mode. In IR
mode function codes 12 to 15 will use SYNC_B. The
PWM output signal is modulated with a 40 kHz carrier
(see Table 3-8). It must be pointed out that the 40 kHz
is derived from the internal clock and will therefore vary
with the same percentage as the baud rate. If IND = 0,
SYNC_A is used for all function codes. If IND = 1, Inde-
pendent mode is enabled and counters for functions
are used according to Table 3-9.
