Description
T16_Enable —Disable/enable the T16 counter. (Note: This register bit
duplicates the function of register bit 7 of the CTR2 register).
Disables the T16 counter if bit 7 of the CTR2 register is also 0.
Enables the T16 counter if bit 7 of the CTR2 register is also 0 and has no effect
if the T16 counter is already enabled by bit 7of the CTR2 register being 1.
T8_Enable —Disable/enable the T8 counter. (Note: This register bit duplicates
the function of register bit 7of the CTR0 register).
Disables the T8 counter if bit 7of the CTR0 register is also 0.
Enables the T8 counter if bit 7of the CTR0 register is also 0 and has no effect if
the T8 counter is already enabled by bit 7of the CTR0 register being 1.
Sync_Mode —When enabled, the first pulse of Timer 8 (the carrier) is always
synchronized with Timer 16 (the demodulated signal). It can always provide a
full carrier pulse. This bit is not reset upon Stop Mode Recovery.
Disable SYNC mode.
Enable SYNC mode.
T16_Out Disable —Set this bit to disable toggling of the Timer 16 output. Time-
out interrupts are still generated. This bit is not reset upon Stop Mode Recovery.
T16 toggles normally.
T16 toggle is disabled.
T8 Demodulate —(Capture one cycle) This bit is not reset upon Stop Mode
Recovery.
T8 captures events normally.
T8 becomes active on the third edge, captures events on the fourth and fifth
edges, and generates an interrupt on the fifth edge. After a T8 time-out the
event count resets to 0 and the fourth and fifth edges are captured again.
Reserved —Always reads 111b. Must be written to 1.
