28 / 62 page GPIO Port BROADCOM September 9, 2013 • 20730-DS108-R Page 27 ® BCM20730 Data Sheet BROADCOM CONFIDENTIAL GPIO Port The BCM20730 has 14 general-purpose I/Os (GPIOs) in the 32-pin package, 22 GPIOs in the 40-pin package, and 40 GPIOs in the 64-pin package. All GPIOs support programmable pull-up and pull-down resistors, and all support a 2 mA drive strength except P26, P27, P28, and P29, which provide a 16 mA drive strength at 3.3V supply. Port 0–Port 1, Port 8–Port 23, and Port 28–Port 38 All of these pins can be programmed as ADC inputs. Port 26–Port 29 P[26:29] consists of four pins. All pins are capable of sinking up to 16 mA for LED. These pins also have the PWM function, which can be used for LED dimming. PWM The BCM20730 has four internal PWM channels. The PWM module consists of the following: •PWM1–4 • Each of the four PWM channels, PWM1–4, contains the following registers: – 10-bit initial value register (read/write) – 10-bit toggle register (read/write) – 10-bit PWM counter value register (read) Table 6: XTAL Oscillator Characteristics Parameter Symbol Conditions Minimum Typical Maximum Unit Output frequency Foscout – – 32.768 – kHz Frequency tolerance – Crystal dependent – 100 – ppm Start-up time Tstartup –– – 500 ms XTAL drive level Pdrv For crystal selection 0.5 – – μW XTAL series resistance Rseries For crystal selection –– 70 k Ω XTAL shunt capacitance Cshunt For crystal selection –– 1.3 pF |
