16.1.2 Registers
16.2 Dependencies
16.2.1 I/O Pins
The output of Timer B does not come out directly on any of the I/O pins. It can be used to
control when the output occurs on Parallel Ports D–E.
16.2.2 Clocks
The timer in Timer B can be clocked by perclk/2, perclk/16, or by countdown Timer A1 as
selected in TBCR.
16.2.3 Other Registers
16.2.4 Interrupts
A Timer B interrupt can be generated whenever the counter equals one of the match
registers by enabling the appropriate bit in TBCSR. The interrupt request is cleared when
TBCSR is read.
