Mode 0. Putting either Timer into Mode 0 makes

it look like an 8048 Timer, which is an 8-bit Counter

with a divide-by-32 prescaler. Figure 22 shows the

Mode 0 operation as it applies to Timer 1.

In this mode, the Timer register is configured as a

13-bit register. As the count rolls over from all '1s'

to all '0s,' it sets the Timer Interrupt Flag TF1. The

counted input is enabled to the Timer when TR1 =

1 and either GATE = 0 or /INT1 = 1. (Setting GATE

= 1 allows the Timer to be controlled by external in-

put /INT1, to facilitate pulse width m easurements).

TR1 is a control bit in the Special Function Regis-

ter TCON (TCON Control Register). GATE is in

TMOD.

The 13-bit register consists of all 8 bits of TH1 and

the lower 5 bits of TL1. The upper 3 bits of TL1 are

indeterminate and should be ignored. Setting the

run flag does not clear the registers.

Mode 0 operation is the same for the Timer 0 as

for Timer 1. Substitute TR0, TF0, and /INT0 for the

corresponding Timer 1 signals in Figure 22. There

are two different GATE Bits, one for Timer 1 and

one for Timer 0.

Mode 1. Mode 1 is the same as Mode 0, except

that the Timer register is being run with all 16 bits.
