Page 3 / Register 16 (0x10): Timer Clock MCLK Divider
READ/ RESET
BIT DESCRIPTION
WRITE VALUE
D7 R/W 1 0: Internal oscillator is used for programmable delay timer.
1: External MCLK
(1)
is used for programmable delay timer.
D6–D0 R/W 000 0001 MCLK Divider to Generate 1-MHz Clock for the Programmable Delay Timer
000 0000: MCLK divider = 128
000 0001: MCLK divider = 1
000 0010: MCLK divider = 2
...
111 1110: MCLK divider = 126
111 1111: MCLK divider = 127
(1) External clock is used only to control the delay programmed between the conversions and not used for doing the actual conversion. This
feature is provided in case a more accurate delay is desired, because the internal oscillator frequency varies from device to device.
