The base timer is a free-running counter that counts an internally generated count source.
Table 13.2 lists specifications of the base timer. Table 13.3 shows registers associated with the base timer.
Figure 13.11 shows a block diagram of the base timer. Figure 13.12 shows an example of the base timer
in counter increment mode. Figure 13.13 shows an example of the base timer in counter increment/decre-
ment mode. Figure 13.14 shows an example of two-phase pulse signal processing mode.

The base timer increments the counter value
The base timer increments/decrements the counter value
Two-phase pulse signal processing
The BTS bit in the G1BCR1 register is set to "1" (base timer starts counting)
The BTS bit in the G1BCR1 register is set to "0" (base timer reset)
(1) The value of the base timer matches the value of the G1BTRR register
(2) The value of the base timer matches the value of G1PO0 register.
(3) Apply a low-level signal ("L") to external interrupt pin,INT1 pin
"0000
The base timer interrupt request is generated:
(1) When the bit 14 or bit 15 in the base timer overflows
(2) The value of the base timer value matches the value of the base timer
reset register (See Figure 13.11)
• The G1BT register indicates a counter value while the base timer is running
• The G1BT register is indeterminate when the base timer is reset
When a value is written while the base timer is running, the timer counter
immediately starts counting from this value. No value can be written while
the base timer is reset.
• Counter increment/decrement mode
"FFFF
timer increments the counter value again when the timer counter reaches
"0000
