New Enhanced Mode 0
For timers T0 or T1 the 13-bit count mode on the 80C51 (current
Mode 0) has been replaced in the XA with a 16-bit auto-reload
mode. Four additional 8-bit data registers (two per timer: RTHn and
RTLn) are created to hold the auto-reload values. In this mode, the
TH overflow will set the TF flag in the TCON register and cause both
the TL and TH counters to be loaded from the RTL and RTH
registers respectively.
These new SFRs will also be used to hold the TL reload data in the
8-bit auto-reload mode (Mode 2) instead of TH.
The overflow rate for Timer 0 or Timer 1 in Mode 0 may be
calculated as follows:
Timer_Rate = Osc / (N * (65536 – Timer_Reload_Value))
where N = the TCLK prescaler value: 4 (default), 16, or 64.
Mode 1
Mode 1 is the 16-bit non-auto reload mode.
Mode 2
Mode 2 configures the Timer register as an 8-bit Counter (TLn) with
automatic reload. Overflow from TLn not only sets TFn, but also
reloads TLn with the contents of RTLn, which is preset by software.
The reload leaves THn unchanged.
Mode 2 operation is the same for Timer/Counter 0.
The overflow rate for Timer 0 or Timer 1 in Mode 2 may be
calculated as follows:
Timer_Rate = Osc / (N * (256 – Timer_Reload_Value))
where N = the TCLK prescaler value: 4, 16, or 64.
Mode 3
Timer 1 in Mode 3 simply holds its count. The effect is the same as
setting TR1 = 0.
Timer 0 in Mode 3 establishes TL0 and TH0 as two separate
counters. TL0 uses the Timer 0 control bits: C/T, GATE, TR0, INT0,
and TF0. TH0 is locked into a timer function and takes over the use
of TR1 and TF1 from Timer 1. Thus, TH0 now controls the “Timer 1”
interrupt.
Mode 3 is provided for applications requiring an extra 8-bit timer.
When Timer 0 is in Mode 3, Timer 1 can be turned on and off by
switching it out of and into its own Mode 3, or can still be used by
the serial port as a baud rate generator, or in fact, in any application
not requiring an interrupt.

FUNCTION
Timer 1 overflow flag. Set by hardware on Timer/Counter overflow.
This flag will not be set if T1OE (TSTAT.2) is set.
Cleared by hardware when processor vectors to interrupt routine, or by clearing the bit in software.
Timer 1 Run control bit. Set/cleared by software to turn Timer/Counter 1 on/off.
Timer 0 overflow flag. Set by hardware on Timer/Counter overflow.
This flag will not be set if T0OE (TSTAT.0) is set.
Cleared by hardware when processor vectors to interrupt routine, or by clearing the bit in software.
Timer 0 Run control bit. Set/cleared by software to turn Timer/Counter 0 on/off.
Interrupt 1 Edge flag. Set by hardware when external interrupt edge detected.
Cleared when interrupt processed.
Interrupt 1 type control bit. Set/cleared by software to specify falling edge/low level triggered
external interrupts.
Interrupt 0 Edge flag. Set by hardware when external interrupt edge detected.
Cleared when interrupt processed.
Interrupt 0 Type control bit. Set/cleared by software to specify falling edge/low level
triggered external interrupts.
