Hard knowledge

16 bit timer B(Timer_B) and timer_ Like a, it is an important resource of MSP430 MCU. Timer_ B is often better than Timer_A more powerful, MSP430F5529 MCU timer_ The B timer has 7 capture / compare registers.

Timer_B. features and structure

       Timer_B timer has the following features:
 asynchronous 16 bit timing / counter with 4 working modes and 4 optional counting lengths;
 the reference clock source can be configured;
 up to 7 configurable capture / comparison registers;
 PWM output capability;
 double buffer comparison latch with synchronous loading capability;
 timer can be_ B interrupt vector register for fast interrupt response.

Timer_B and timer_ The differences of a are listed as follows:
① Timer_B count length is 8 bits, 10 bits, 12 bits and 16 bits programmable, while timer_ The counting length of a is fixed to 16 bits.
② Timer_B does not implement timer_ Function of SCCI register bit in a.
③ Timer_B capture / compare register function and timer in comparison mode_ A is different, and a comparison latch is added.
④ Timers in some models of chips_ B output realizes high impedance output.
⑤ The principle of comparison mode is different. In timer_ In a, the CCRx register stores the data compared with TAR, and in timer_ In B, the data to be compared is stored in the CCRx register, but it is not directly compared with the timing counter TBR. After CCRx is sent to the corresponding latch, the latch is compared with the timing counter TBR. The timing of transmitting data from the capture / comparison register to the comparison latch can also be programmed, which can be transmitted immediately after writing to the capture / comparison register, or triggered by a timing event.
⑥ Timer_B supports multiple synchronous timing functions, multiple capture / comparison functions and multiple waveform output functions. Moreover, through the two-stage buffer of the comparison data, the synchronous update of multiple PWM signal cycles can be realized.

Timer_B register

Timer_ The list of B registers is shown in the table, and the base address is 03C0h.

Timer B API

TIMER_ The B API is divided into three groups of functions:
Functions that handle timer configuration and control
Functions that handle timer output
Functions that handle interrupt handling
