Description
Timer 2 data high byte.
As the count rolls over from all 1s to all 0s, it sets the timer
overflow flag, TF0 (Address 0x88[5]). TF0 can then be used to
request an interrupt. The counted input is enabled to the timer

(TCON, Address 0x88); the Gate0/Gate1 bits are in
Timer/Counter 0 and Timer/Counter 1 mode SFR (TMOD,
Address 0x89). The 13-bit register consists of all eight bits of
Timer 0 high byte SFR (TH0, Address 0x8C) and the lower five
bits of Timer 0 low byte SFR (TL0, Address 0x8A). The upper
three bits of TL0 SFR are indeterminate and should be ignored.
Setting the run flag (TR0) does not clear the registers.
