REGISTER 13-1: TXCON: TYPE B TIMER CONTROL REGISTER (CONTINUED)

bit 3

T32: 32-Bit Timer Mode Select bit(2)

1 = Odd numbered and even numbered timers form a 32-bit timer

0 = Odd numbered and even numbered timers form a separate 16-bit timer

bit 2

Unimplemented: Read as ‘0’

bit 1

TCS: Timer Clock Source Select bit(3)

1 = External clock from TxCK pin

0 = Internal peripheral clock

bit 0

Unimplemented: Read as ‘0’

Note 1:

2:

3:

4:

When using 1:1 PBCLK divisor, the user’s software should not read/write the peripheral SFRs in the

SYSCLK cycle immediately following the instruction that clears the module’s ON bit.

This bit is available only on even numbered timers (Timer2 and Timer4).

While operating in 32-bit mode, this bit has no effect for odd numbered timers (Timer1, Timer3, and

Timer5). All timer functions are set through the even numbered timers.

While operating in 32-bit mode, this bit must be cleared on odd numbered timers to enable the 32-bit timer

in Idle mode.
