Register Description
TIMER A CONTROL STATUS REGISTER (TIMCSRA)
Read/Write
Reset Value: (00h)
Bits [7:6] = TB[1:0]
Time Base period selection
These bits are set and cleared by software.
00 Time base period = t
TIMER

01 Time base period = t
TIMER
x 8 (2048 μs @ 8 MHz)
10 Time base period = t
TIMER
x 64 (16384 μs @ 8 MHz)
11 Reserved
Bit 5 = OVF
Timer Overflow Flag.
This bit is set by hardware. An interrupt is generated if OVFE = 1. It must be cleared by reading the
TIMCSRA register.
0
No timer overflow.
1
The free-running downcounter reached 00h.
Bit 4 = OVFE
Timer Overflow Interrupt Enable.
This bit is set and cleared by software.
0
Interrupt disabled
1
Interrupt enabled
Bit 3 = TAR
Timer Auto-Reload
This bit is set and cleared by software.
0
One-shot mode. The counter restarts after a write in the TIMCPRA register.
1
Auto-Reload mode. The counter is reloaded automatically by the TIMCPRA register after the
downcounter reaches 00h.
Bits [2:1] = BUZ[1:0]
Buzzer tone selection
These bits are set and cleared by software.
00 Time base frequency = f
