Standard Timer (TIM)
12.3.13 Timer Test Register
Read: Anytime
Write: Only in special mode (SMODN = 0)
TCBYP — Timer Divider Chain Bypass Bit
PCBYP — Pulse Accumulator Divider Chain Bypass Bit
12.3.14 Timer Port Data Register
Read: Anytime; inputs return pin level; outputs return pin driver input level
Write: Data stored in an internal latch; drives pins only if configured for output

0 = Normal operation
1 = 16-bit free-running timer counter is divided into two 8-bit halves and the prescaler is bypassed.
0 = Normal operation
1 = 16-bit pulse accumulator counter is divided into two 8-bit halves and the prescaler is bypassed.
The clock drives both halves directly.
The clock drives both halves directly.
Address: $00AD
Address: $00AE
Writes do not change pin state when the pin is configured for timer output.
The minimum pulse width for pulse accumulator input should always be
greater than two module clocks due to input synchronizer circuitry. The
minimum pulse width for the input capture should always be greater than
the width of two module clocks due to input synchronizer circuitry.
