Note: DISIAPL pin in PLCC or TQFP will also disable IAP commands if it is externally pulled low when reset.
5.0 TIMERS/COUNTERS
5.1 Timers
The device has three 16-bit registers that can be used as
either timers or event counters. The three timers/counters
are denoted Timer 0 (T0), Timer 1 (T1), and Timer 2 (T2).
Each is designated a pair of 8-bit registers in the SFRs.
The pair consists of a most significant (high) byte and least
significant (low) byte. The respective registers are TL0,
TH0, TL1, TH1, TL2, and TH2.
5.2 Timer Set-up
Refer to Table 3-8 for TMOD, TCON, and T2CON registers
regarding timers T0, T1, and T2. The following tables pro-
vide TMOD values to be used to set up Timers T0, T1, and
T2.
Except for the baud rate generator mode, the values given
for T2CON do not include the setting of the TR2 bit. There-
fore, bit TR2 must be set separately to turn the timer on.

1. SFCF[6]=1 enables IAP commands; SFCF[6]=0 disables IAP commands.
2. Interrupt/Polling enable for flash operation completion
SFCM[7] = 1: Interrupt enable for flash operation completion
0: polling enable for flash operation completion
3. Chip-Erase only functions in IAP mode when EA#=0 (external memory execution) and device is not in level 4 locking.
4. X can be VIL or VIH, but no other value.
5. AH = Address high order byte
6. AL = Address low order byte
7. DI = Data Input, DO = Data Output, all other values are in hex.
8. SFAH[7:5] = 111b selects Block 1, SFAH[7] = 0b selects Block 0
9. Instruction must be located in Block 1 or external code memory.

Internal
Control1
1. The Timer is turned ON/OFF by setting/clearing
bit TR0 in the software.
External
Control2
2. The Timer is turned ON/OFF by the 1 to 0 transition
on INT0# (P3.2) when TR0 = 1 (hardware control).
