Timer 2 Clock Select. This bit controls the division of the system clock that drives Timer 2. This bit has no effect when
bit 5
the timer is in baud rate generator or clock output modes. Clearing this bit to 0 maintains 8051 compatibility. This bit
has no effect on instruction cycle timing.
0: Timer 2 uses a divide by 12 of the crystal frequency.
1: Timer 2 uses a divide by 4 of the crystal frequency.
T1M
Timer 1 Clock Select. This bit controls the division of the system clock that drives Timer 1. Clearing this bit to 0
bit 4
maintains 8051 compatibility. This bit has no effect on instruction cycle timing.
0: Timer 1 uses a divide by 12 of the crystal frequency.

Timer 0 Clock Select. This bit controls the division of the system clock that drives Timer 0. Clearing this bit to 0
bit 3
maintains 8051 compatibility. This bit has no effect on instruction cycle timing.
0: Timer 0 uses a divide by 12 of the crystal frequency.
1: Timer 0 uses a divide by 4 of the crystal frequency.

Stretch MOVX Select 20. These bits select the time by which external MOVX cycles are to be stretched. This
bits 20
allows slower memory or peripherals to be accessed without using ports or manual software intervention. The
width of the RD or WR strobe will be stretched by the specified interval, which will be transparent to the software
except for the increased time to execute the MOVX instruction. All internal MOVX instructions on devices
containing MOVX SRAM are performed at the 2 instruction cycle rate.
