User’s Manual U16580EE3V1UD00
11.6.9 Encoder count function
The encoder compare mode is provided as follows.
(1)
Counter up/down control
Counter up/down control is performed and the counter is operated according to the phase of
signals TENCTn0 and TENCTn1 from the encoder and the set conditions of bits TTnUDS1 and
TTnUDS0 of the TTnCTL2 register.
(2)
Basic operation
To use the TTnCCR0 and TTnCCR1 registers are compare-only registers, enable rewrite during
timer operation.
The rewrite method is anytime write.
A compare match interrupt (INTTTnCC0) is output upon a match between the counter and
TTnCCR0 register. A compare match interrupt (INTTTnCC1) is output upon a match between the
counter and TTnCCR1 register.
(3)
Counter clear operation
Clearing of the counter to 0000H is performed under the following conditions.
Mode
TTnCCR0 register
TTnCCR1 register
Encoder compare mode
Compare only
Compare only
Clear Condition
Method whereby counter is cleared to 0000H upon match with
compare register (setting of TTnCTL2 register bits TTnECM1,
TTnECM0)
√
Method whereby counter is cleared to 0000H upon detection of
edge of pin TECRT0 (setting of bits TTnECS1, TTnECS0 when
TTnIOC3 register bit TTnSCE = 0)
√
Method whereby counter is cleared to 0000H by special clear
function of encoder
(setting of bits TTnZCL, TTnBCL, TTnACL when TTnIOC3
register bit TTnSCE = 1)
