Bit 6:0 = T[6:0] 7-bit timer (MSB to LSB).

These bits contain the decremented value. A reset

is produced when it rolls over from 40h to 3Fh (T6

becomes cleared).

Bit 7 = WDGA Activation bit.

This bit is set by software and only cleared by

hardware after a reset. When WDGA = 1, the

watchdog can generate a reset.

0: Watchdog disabled

1: Watchdog enabled

Note: This bit is not used if the hardware watch-

dog option is enabled by option byte.
