Configure GPIOB2 (CFG_B2)—Bit 6
0 = MISO (default)
1 = T2
6.3.8.10 Configure GPIOB1 (CFG_B1)—Bit 5
This bit selects the alternate function for GPIOB1.
0 = SS (default)
1 = SDA
6.3.8.11 Configure GPIOB0 (CFG_B0)—Bit 4
This bit selects the alternate function for GPIOB0.
0 = SCLK (default)
1 = SCL
6.3.8.12 Configure GPIOA5[1:0] (CFG_A5)—Bits 3–2
These bits select the alternate function for GPIOA5.
00 = Select PWM5 when peripheral mode is enabled in GPIOA5 (default)
01 = Select PWM5 when peripheral mode is enabled in GPIOA5
10 = Select FAULT2 when peripheral mode is enabled in GPIOA5
11 = Select T3 when peripheral mode is enabled in GPIOA5
6.3.8.13 Configure GPIOA4[1:0] (CFG_A4)—Bits 1–0
These bits select the alternate function for GPIOA4.
00 = Select PWM4 when peripheral mode is enabled in GPIOA4 (default)
01 = Select PWM4 when peripheral mode is enabled in GPIOA4
10 = Select FAULT1 when peripheral mode is enabled in GPIOA4
11 = Select T2 when peripheral mode is enabled in GPIOA4
6.3.9
The Peripheral Clock Enable register is used to enable or disable clocks to the peripherals as a power
savings feature. The clocks can be individually controlled for each peripheral on the chip. The
corresponding peripheral should itself be disabled while its clock is shut off. IPBus writes cannot be made
to a module that has its clock disabled.
