Chapter 11 Flexible Timer (FTM)
[1]
Timer Register (TMR16)
A timer register consists of 16 bits (TMR16). In the case of RTO operation, TMR16 is
constantly compared with the counter value specified by TMSEL2. In the case of CAP
mode, the counter value specified by TMSEL2 is loaded to the timer register when a pin
event is generated.
TMR16 can be read/written by the program. 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), TMR16 becomes 0000H.

Real-time Output Control Register (RTOCON16)
A real-time output control register (RTOCON16) consists of 3 bits. When TMR16 is in
RTO mode, if TMR16 matches the counter value specified by TMSEL2, the content of
T16BF0 (bit 1) is loaded to T16OUT (bit 0). Set the state for the next event to T16BF0.
RTOCON16 can be read/written by the program. Write is valid, however write to high-
order 5 bits is invalid. Read is valid, however "1" is always read from the high-order 5
bits. If a read-modify-write instruction, such as SB, RB, and XORB, is executed to
RTOCON16 just prior to an event generated by RTO, T16BF0 and T16OUT may not
operate normally.
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), RTOCON16 becomes F8H.
Figure 11-32 shows the configuration of RTOCON16.

When TMR16 is in RTO mode, the
content of this flag is output to a
FTM16 pin.
When TMR16 is in RTO mode, if the
selected counter value and the TMR16
value match, the content of this flag
is loaded to T16OUT.
When TMR16 is in CAP mode, if the
selected counter completes one
cycle during a capture event, the
content of this flag is "1", if not, "0".
"—" indicates a bit that is not provided.
"1" is read if a read instruction is executed.
