T2THD (0xA7) – Timer 2 Timer Value High Byte

Bit

Name

Reset

R/W

Description

7:0

THD[7:0]

0x00

R/W

The value read from this register is the high-order byte of the timer

value. The high-order byte read is from timer value at the last instant

when

T2TLD was read.

The value written to this register while the timer is running is the high-

order byte of the timer delta counter value. The low-order byte of this

value is the value last written to

T2TLD. The timer will halt for delta

clock cycles.

The value written to this register while the timer is idle will be written to

the high-order byte of the timer.

T2TLD (0xA6) – Timer 2 Timer Value Low Byte

Bit

Name

Reset

R/W

Description

7:0

TLD[7:0]

0x00

R/W

The value read from this register is the low-order byte of the timer value.

The value written to this register while the timer is running is the low-

order byte of the timer delta counter value. The timer will halt for delta

clock cycles. The value written to T2TLD will not take effect until T2THD

is written.

The value written to this register while the timer is idle will be written to

the low-order byte of the timer.

T2CMP (0x94) – Timer 2 Compare Value

Bit

Name

Reset

R/W

Description

7:0

CMP[7:0]

0x00

R/W

Timer Compare value. A timer compare occurs when the compare

source selected by T2CNF.CMSEL equals the value held in CMP.

T2OF2 (0xA3) – Timer 2 Overflow Count 2

Bit

Name

Reset

R/W

Description

7:4

0000

Not used, read as 0

3:0

OF2[3:0]

0x00

R/W

Overflow count. High bits T2OF[19:16]. T2OF is incremented by 1

each time the timer overflows i.e. timer counts to a value greater or

equal to period. When reading this register, the value read is the value

latched when T2OF0 was read. 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.
