Specification
Count source
f1, f8, f32, fC32
Count operation
Counts down
When the timer underflows, it reloads the reload register contents before
continuing counting
Divide ratio
1/(n+1)
n : Set value
Count start condition
Count start flag is set (= 1)
Count stop condition
Count start flag is reset (= 0)
Interrupt request generation timing
The timer underflows
TBiIN pin function
Programmable I/O port
Read from timer
Count value is read out by reading timer Bi register
Write to timer
When counting stopped
When a value is written to timer Bi register, it is written to both reload register and counter
When counting in progress
When a value is written to timer Bi register, it is written to only reload register
(Transferred to counter at next reload time)
(1) Timer mode
In this mode, the timer counts an internally generated count source. (See Table 1.13.6.) Figure 1.13.17
shows the timer Bi mode register in timer mode.
Table 1.13.6. Timer specifications in timer mode
Note 1: Timer B0, timer B3.
Note 2: Timer B1, timer B2, timer B4, timer B5.

Count source select bit
0
0 (Fixed to “0” in timer mode ; i = 0, 3)
Nothing is assiigned (i = 1, 2, 4, 5).
In an attempt to write to this bit, write “0”. The value, if read, turns out
to be indeterminate.
(Note 1)
(Note 2)
b7 b6
Invalid in timer mode.
In an attempt to write to this bit, write “0”. The value, if read in
timer mode, turns out to be indeterminate.

Note: Timer B1 works exclusively as an internal timer since timer B1 does not have input port (TB1IN).
