Gate control.
When GATE = 1, T/C is enabled only while pin
EXTINT1 is '1' and the flag TR1 is '1.' When GATE = 0,
T/C is enabled whenever the flag TR1 is '1.'
Counter or Timer function select.
When C/T = 0, function is timer, clocked by internal
clock. C/T = 1, function is counter, clocked by signal
sampled on external pin, C1.
Mode Select.
00b = 13-bit T/C. 8 bits in TH1 with TL1 as 5-bit pre-
scaler.
01b = 16-bit T/C. TH1 and TL1 are cascaded. No pre-
scaler.
10b = 8-bit auto-reload T/C. TH1 holds a constant and
loads into TL1 upon overflow.
11b = Timer Counter 1 is stopped.
Gate control.
When GATE = 1, T/C is enabled only while pin
EXTINT0 is '1' and the flag TR0 is '1.' When GATE = 0,
T/C is enabled whenever the flag TR0 is '1.'
Counter or Timer function select.
When C/T = 0, function is timer, clocked by internal
clock. C/T = 1, function is counter, clocked by signal
sampled on external pin, C0.
Mode Select.
00b = 13-bit T/C. 8 bits in TH0 with TL0 as 5-bit pre-
scaler.
01b = 16-bit T/C. TH0 and TL0 are cascaded. No pre-
scaler.
10b = 8-bit auto-reload T/C. TH0 holds a constant and
loads into TL0 upon overflow.
11b = TL0 is 8-bit T/C controlled by standard Timer 0
control bits. TH0 is a separate 8-bit timer that uses
Timer 1 control bits.
