T2OF0 (0xA1) – Timer 2 Overflow Count 0
Bit
Name
Reset
R/W
Description
OF0[7:0]
7:0
0x00
R/W
Overflow count. Low bits T2OF[7:0]. T2OFis incremented by 1 each
time the timer overflows i.e. timer counts to a value greater or equal to
period. Writing to this register when the timer is in IDLE or RUN states
will force the overflow count to be set to the value written to
T2OF2:T2OF1:T2OF0. If the count would otherwise be incremented by
1 when this register is written then 1 is added to the value written. The
value written will not take effect until T2OF2is written.
T2CAPHPH (0xA5) – Timer 2 Period High Byte
Bit
Name
Reset
R/W
Description
7:0
CAPHPH[7:0]
0xFF
R/W
Capture value high/timer period high. Writing this register sets the high
order bits [15:8] of the timer period. Reading this register gives the high
order bits [15:8] of the timer value at the last capture event.
T2CAPLPL (0xA4) – Timer 2 Period Low Byte
Bit
Name
Reset
R/W
Description
CAPLPL[7:0]
7:0
0xFF
R/W
Capture value low/timer period low. Writing this register sets the low
order bits [7:0] of the timer period. Reading this register gives the low
order bits [7:0] of the timer value at the last capture event.
T2PEROF2 (0x9E) – Timer 2 Overflow Capture/Compare 2
Bit

PEROF2[3:0]
3:0
0000
R/W
Overflow count capture/Overflow count compare value. Writing these
bits set the high bits [19:16] of the overflow count compare value.
Reading these bits returns the high bits [19:16] of the overflow count
value at the time of the last capture event.
T2PEROF1 (0x9D) – Timer 2 Overflow Capture/Compare 1
Bit
Name
Reset
R/W
Description
PEROF1[7:0]
7:0
0x00
R/W
Overflow count capture /Overflow count compare value. Writing these
bits set the middle bits [15:8] of the overflow count compare value.
Reading these bits returns the middle bits [15:8] of the overflow count
value at the time of the last capture event.
