TIMER2—Timer Register 2
The TIMER1 and TIMER2 register contents can be used to generate a low-frequency clock signal on a GPIO_ output.
The low-frequency clock is a divided replica of the fractional divider output.
Bit 7: TmrToGPIO
Set TmrToGPIO to 1 to enable clock generation at a GPIO output. The clock signal is routed to a GPIO output as fol-
lows: UART0 clock signal to GPIO1, UART1 clock signal to GPIO5, UART2 clock signal to GPIO9, UART3 clock signal
to GPIO13. The output clock has a 50% duty cycle.
Bits 6–0: Timer[n]
Timer[14:8] are the 7 MSBs of the 15-bit timer divisor. The clock frequency is calculated using the following formula:
fTIMER_CLK = UARTClk/(1024 x Timerx)
where UARTClk is the fractional baud-rate generator output (i.e. 16 x BaudRate). When using 2x or 4x rate modes,
UARTClk is 8 x BaudRate or 4 x BaudRate, respectively.
If TIMER1 and TIMER2 are both 0x00, the low-frequency clock is off.
RevID—Revision Identification Register
Bits 7–0: Bit[n]
The RevID register indicates the revision number of the MAX14830 silicon—starting with 0xB1. This can be used during
software development as a known reference.
