PIC32MX FAMILY
EXAMPLE 11-2:
DS61143A-page 238
// Code example to change the PBCLK divisor
// This example is for a device running at 40 MHz
// Make sure that there is no UART send/receive in progress
... user code ...
U1BRG = 0x81;
... user code ...
OSCCONCLR = 0x3 << 19;
... user code ...
// Change Peripheral Clock value
U1BRG = 0x0F;
OSCCONSET = 0x3 << 19;
// Reset Peripheral Clock
OSCCONCLR = 0x3 << 19;
U1BRG = 0x81;
CHANGING THE PB CLOCK DIVISOR
// set baud rate for UART1 for 9600
// set PB divisor to minimum (1:1)
// set baud rate for UART1 for 9600 based on
// new PB clock frequency
// set PB divisor to maximum (1:8)
// set PB divisor to minimum (1:1)
// restore baud rate for UART1 to 9600 based
// on new PB clock frequency
