11.4 Type A2 Register Modules (TMR14, TMR15)
The MSM66591/ML66592 have two sets of type A2 register modules (TMR14, TMR15).
The configuration is the same for the two sets, except for the address of registers on
SFR.
11.4.1 Configuration of Type A2 Register Modules (TMR14, TMR15)
Type A2 register modules have a 16-bit capture input function.
Type A2 register modules consist of a 16-bit timer register (TMRn), a pin to input
external events (CAPn), the edge detection of an external event, a divider to divide an
external event, a timing controller, and control registers (CAPCON, EVNTCON2) to
specify the operation of the valid edge of an external event and the operation of a
divider.
If CAP14 and CAP15 pins are used as a capture function, set the bit corresponding to
the Port 10 secondary function control register to "1".
Figure 11-14 shows the configuration of a type A2 register module.

Timer Registers (TMR14, TMR15)
The timer registers consist of 16 bits. The counter specified by TMSEL is connected to
TMR14 and TMR15. If the specified valid edge is input to CAP14 and CAP15 for the
specified number of pulses, a capture event is generated. When a capture event is
generated, the 16-bit content of the counter specified by TMSEL is loaded into TMR14
and TMR15.
The program can read from but not write to TMR14 and TMR15.
At reset (when the
RES
signal is input, the BRK instruction is executed, the watchdog
timer is overflown, or an operation code trap is generated), TMR14 and TMR15 are
undefined.
