13 16-BiT PWM TiMeRS (T16a2)
T16a Comparator/Capture Ch.x a Data Registers (T16a_CCax)
Register name address Bit
T16a 0x5406 D15–0 CCa[15:0]
Comparator/ 0x5426
Capture Ch.x a (16 bits)
Data Register
(T16a_CCax)
D[15:0] CCa[15:0]: Compare/Capture a Data Bits
In comparator mode (CCAMD/ T16A_CCCTLx register = 0)
Sets a compare A data, which will be compared with the counter value, through this register.
The counter value comparison timing varies according to the CBUFEN/T16A_CTLx register value. For
more information, see "Comparator mode (CCAMD/CCBMD = 0, default)" in Section 13.4.1.
note: After the T16A_CCAx register has been set, wait for one or more T16A2 count clock cycles
and then run the counter.
In capture mode (CCAMD = 1)
When the counter value is captured at the external trigger signal (CAPAx) edge selected using
CAPATRG[1:0]/T16A_CCCTLx register, the captured value is loaded to this register. At the same time
a capture A interrupt can be generated, thus the captured counter value can be read out in the interrupt
handler.
T16a Comparator/Capture Ch.x B Data Registers (T16a_CCBx)
Register name address Bit
T16a 0x5408 D15–0 CCB[15:0]
Comparator/ 0x5428
Capture Ch.x B
(16 bits)
Data Register
(T16a_CCBx)
D[15:0] CCB[15:0]: Compare/Capture B Data Bits
In comparator mode (CCBMD/ T16A_CCCTLx register = 0)
Sets a compare B data, which will be compared with the counter value, through this register.
The counter value comparison timing varies according to the CBUFEN/T16A_CTLx register value. For
more information, see "Comparator mode (CCAMD/CCBMD = 0, default)" in Section 13.4.1.
note: After the T16A_CCBx register has been set, wait for one or more T16A2 count clock cycles
and then run the counter.
In capture mode (CCBMD = 1)
When the counter value is captured at the external trigger signal (CAPBx) edge selected using CAPB-
TRG[1:0]/T16A_CCCTLx register, the captured value is loaded to this register. At the same time a
capture B interrupt can be generated, thus the captured counter value can be read out in the interrupt
handler.
