REMOUT
Following is a description of the associated registers (see the
block diagram):
Carrier Generator
This block is the same circuit as used in the soft-timer
mode. The associated registers are REMC, RCDIV and
RCDUTY all of which are set in the same way as in the
soft-timer mode. The difference is that the REMSO regis-
ter must be fixed at 0.
τ (Reference Cycle) Generator
This block generates the cycle
τ which gives a reference
time for REMOUT and REM interrupts. The reference
cycle
τ is produced by dividing the REM carrier fre-
quency.
The division ratio is defined by RT1 (0F7H, D1) and RT0
(0F7H, D0). (See Table 3.9.4.)
